Do Not Trust Stax and Fiserv
My company had a VERY disappointing experience with Stax and Fiserv which has cost our company thousands of dollars. We had a spammer attack our business 1/2/26 and attempt to register for our program over 20,000 times. This resulted in our account being frozen with Stax, Authorize, and Fiserv so we could not provide any refunds, or process any transactions. We contacted Stax and tried to start the process of resolving this issue. It took stax days to respond and they did not offer any help. Our ticket was then escalated to Katherine. We set up a phone call with her on 1/13 for the next day (1/14). We did not receive a call and we followed up, she stated her meeting ran late and she would call shortly. I made another appointment for 2:15 and we did not receive a call. We requested to be connected with a supervisor which Katherine refused. Katherine told us to contact Fiserv as the block was coming from them, but Fiserv would not speak with us and would only speak with stax. We were unable to resolve the issue on our own. We then waited another week to get an answer from Stax/Fiserv. My management left a review on here and we were only contacted AFTER they read our review to try and convince us to remove the review. They FINALLY found the issue after this and after ONE MONTH of not being able to refund customers, we were able to access that feature again. We had to switch from Authorize to Stripe to be able to continue our business. During that month, we were notified of a chargeback due to not being able to refund anyone. We were charged $15 on stripe for the chargeback PLUS an international card fee. When I tried to speak to Authorize, Stax and Fiserv, they said there was nothing they could do and we would just have to accept the chargeback and pay the fees, even though it was not our fault that we could not provide the refund. In early February, $18,000 was taken from our bank account due to the processing fees associated with the fraud attempt. Fiserv and Stax will not respond to our emails to discuss these fees. These fees were due to Fraud and they will not provide a refund or discount even though it took them over ONE MONTH to resolve this issue. Do not trust this company with your business. They do not care about your business and will take months to find the issue they created.
