Thieves.
Thieves.. Fake delivery company used by AliExpress sellers to take advantage of a loophole that lets them rob you. They 'send' the parcel, say there was an error with your address, then the system demands that YOU contact the courier to resolve it. The courier can't be contacted and just has a standard email saying "sorry we couldn't deliver your package" (but no identifying details e.g. tracking number or item number, so it doesn't count as 'evidence' to Aliexpress). You can take all your evidence, their own website even saying the parcel was returned to the seller, and you can have it 'escalated' to all the 'senior teams' you like, hell I took myself through it 8 times, but you wont get your money back. They're all in cahoots, and this is how AliExpress is now a scam site.
