Trying to order something on a website was not working at the payment step, I tried everything like removing the accent in my name, changing my delivery address, paying with different cards, changing delivery method.
The phone support told me I should see with my bank, but offered to generate an order with a link to pay, so we tried this and it didn't work.
Then, after a second call, I've been told that it was certainly my bank because they spent 10 minutes investigating and they do not block anything, and just at the end, they told me that I should try with a @gmail.com address because they have a system that may block orders from "suspicious addresses". I changed my email to something else (not gmail.com though :D ) and it worked
-_-
Who decided there that gmail.com addresses are more legit than others? Most of the scam I receive is sent from gmail :flan_molotov: :flan_bored:
