I used to be a BT customer but switched fully over to another provider. I now want to enrol for BT Sport and I am using the same details as my previous account when signing up.
I get this error at the point where it is loading the card payment inline window:
I've tried enrolling via pc, laptop, and mobile browsers to no avail. and also with wifi and data connections.
All add-ons/adblockers etc have been disabled.
Same happens each time. I googled and there was some stuff about unusual characters but that doesn't fit my issue - my email address is simply my email@example.com
My password is v. complex with multiple special chars etc but that's normal.
