Just received an email from Asurion on Friday about a mobile I traded in was still locked and if not unlocked they would bill me after 10 days
Today I got an email from them that they would charge me the $10. So they gave me 1 business day (or 3 days inc weekend). I did unlock the device too. But knowing how bad their department it, it wouldn't have been read.
Here's the crazy part though, this was a trade in that I did 13 months ago!! Im pretty sure I used a card that I have also cancelled since then.
They charged me a few months ago for a traded in S21 ultra, never read my responses that the device had been unlocked and then got them to refund me which took a couple of months too.
Then just head from one of my friends that they got charged too by Asurion that the device was never received even though tracking showed it was received, but he was too lazy to do anything about it.
I know its only $10 this time but its the principle of the matter
Make sure your card is cancelled. But this is where marketplace and ebay is no doubt better
