Refusal to cancel orders despite inaccurate lead time information
I have ordered the product with 3-4 weeks lead time on May 2026 , but the store have postponed me the shipment 3 times until Mid July and informed me still unknown the shipment date yet. Then I decide to purchase the product from other sellers instead and request to cancel the order, the store have not accepted to cancel the order and start the shipment to me on the end of July.

We're sorry for the delays and the inconvenience this caused, Pongthorn. Unfortunately, unexpected manufacturer production delays impacted your order. When you requested to cancel, an internal processing error allowed the order to ship before it could be stopped. We've issued a return authorization and provided a prepaid return label. We apologize again and appreciate the opportunity to make this right.
Really disappointed in the service from this company. We ordered an item, that had a one - two week lead time. When it arrived two weeks later, they had shipped us the completely wrong item in the box. Disappointing, but mistakes happen. What matters is how mistakes are handled.
Called customer service, and they said I needed to email. So I emailed and the auto response said someone would respond in 1 - 2 days. I never did receive a response to that email. I called and talked to 4 different customer service reps over a 2 week period. While 3 out of the 4 were pleasant to talk with and professional, there was very little willingness to actually do anything to resolve the issue. That other rep- we will just consider them an outlier. They were the most unprofessional and infuriating rep I have spoken to in a long time. She was very concerned with processing the return of the wrong item, and seemed to totally ignore that I still needed to receive the right item. She said once they had the wrong ($38) item back in their hands then they would look into getting me the correct ($200) item figured out. This is not acceptable, since at this point I was already three weeks and 3 phone calls into trying to correct THEIR mistake. It was never my mistake. This rep also insisted the mistake was the fault of the manufacturer, not them, but that is ridiculous since it was clearly repackaged by GTS and they shipped me an item from a completely different manufacturer.
They finally, a week later, decided to send me a shipping label to send my received item to the person who should have received it, and sent them a label to send it to me. So I spend time acting as their shipping employee by repackaging it, taking their terribly scanned and crooked shipping label and image processing it so I could actually print it from my label printer, and shipped the item out. Then I just have to wait and hope the other company actually did the same, but I have no way of knowing since I don't have a tracking number. Finally 4+ weeks after my initial order the item arrived, but long past when I needed it. In the end, it arrived too late for the project, I had to put time in to correct their mistake, and it took over a month to receive it.
The result? No offer of any sort of refund, even just for the shipping cost even though they never actually did ship me the right item, that came from another one of their customers who thankfully did actually choose to send the item. I had to down sell my client because the item we upsold them on never arrived before we had to ship the final product out. So now I have an item I don't really need anymore sitting around hoping to need it on a future product, and I lost money because I did the right thing with my client by honoring my commitments, even though GTS didn't. And I spent an obnoxious amount of time trying to get this figured out. GTS is now on our vendor blacklist as we cannot trust this company with future business.
Only reason it is 2 stars instead of one is because I was impressed at how easy it was to get a representative on the phone all 4 times that I called, and 3/4 spoke English very well and were professional, even if they were not completely helpful. That 4th customer service rep 100% would not represent my company
In fact, they actually sent my this request to review before they even managed to get the correct item in my hands.
Edit: Bumped up from 2 to 3 stars since they did reach out and offer to help make it right. Honest mistakes happen in every business, but how it was handled initially was not acceptable. I appreciate that they took ownership of the mistake though, as not every business these days is willing to admit a mistake.

We have addressed the issues internally, including coaching opportunities where appropriate, and worked directly with you to reach a mutually agreeable resolution.

Global Test Supply had lower prices, fast shipping and quality tools. The prices were even lower than eBay for the item I purchased.

Thank you for sharing your 5-star review with us, Marvin! We're happy to hear you're enjoying our competitive prices and that your product arrived in a timely manner. We look forward to working with you again soon.
If there was an option to give zero stars I would give that. Horrible customer service, slow and my issue has not been resolved. Do not use this website.

We've addressed this internally, and your refund is now being processed. We appreciate your feedback and apologize that we fell short of the level of service you expected.

We're sorry your order took longer to arrive than expected, Mike, and that you didn't receive the follow-up you were expecting. We understand the importance of providing timely updates, and we apologize that your experience fell short of your expectations. We appreciate you taking the time to share your feedback, as it helps us improve our communication and service.
Global test supply charged my credit card at the time of ordering and again when shipped.
Reply from Global Test Supply2026-07-16
Thank you for sharing your concerns, Royce. After reviewing your account, we confirmed that you were only charged once. The first amount shown was a temporary authorization from your card issuer to verify the funds, and when your order shipped, that authorization was finalized as the actual charge rather than creating a second charge. We understand how this can appear confusing on a bank statement and appreciate the opportunity to clarify.
Could not even get an email to register for this junk site. Called their technical support and it was as useless as the site itself.

I ordered and paid upfront 3 parts supposed to be available within 1 week on May the 8th 2026. Since then it hasn't been shipped and the shipping date keeps sliding, now it is on the 14th of July 2026.
As of now the item is still listed as ready within 5 days on the website, this is false advertisement and total customer scam.
Update 15/07/2026:
Global Test Supply’s response below is pure PR theater. I emailed their support team at the exact address provided with all of my order details immediately after they replied here.
They have completely ignored my emails and have not responded since. They can "locate" my order perfectly fine in their system—they just choose to ignore it while pretending to care in the public comments. Still no item, still no customer service. Avoid this company.

We sincerely apologize for the delay you experienced with your order, Benjamin. After reviewing your case, we confirmed that the delay was caused by unforeseen supply issues from the manufacturer, who was unable to meet both the original and revised shipping dates. We understand your concern regarding the lead time displayed on our website and have updated it to better reflect current supplier lead times. We can also confirm that your order is now being prepared for shipment and is expected to ship today or tomorrow. We appreciate your patience and your feedback as we continue working to improve the accuracy of the information we provide.
I was very pleased with my purchase at GTS. The price was great and the processing was easy and fast. The calipers are great and of excellent quality, I can already tell they are much more precise than the ones I was using prior. I would and will recommend GTS for quality equipment anytime and anyone. Thanks GTS!

I bought an Autel scanner. I was skeptical with a discounted price, but it was perfect. My order was backordered so delivery took a little while. Great experience overall.
