Try it again and change everything even the computer you order from. Use completely new details that you have never used with asos before even if the transaction was refused.

it's the 7th account I'm creating, the only thing I can't change is the name and surname of the card. but I have also used other cards from other banks

Most likely they banned your IP, blocked your card and any linkage in cardholder details. Somehow big brands can identify the cardholder of a specific card. Even though, name of cardholder may not be required upon payment. Not sure if that’s the case with ASOS. Nonetheless, point is that companies can detect correlation in card’s registered address and billing address / delivery address. If they don’t match the systems flag the transaction and often times leads to order cancellations, etc.
Thus , VPN may not work (not sure if that’s the case with ASOS) But when ordering the app / website doesn’t allow you to purchase with a VPN because they need to know exactly in what country you live so they can delivery accordingly and obviously prevent fraudulent activities.This is the case with Nike, example.
