So I struggled to delete a free Apple TV+ account for a day now (tried different browsers etc) and decided to search if anyone else has had the same problem. Turns out this issue is at least a year old, is known by apple and the Apple support suggests to find someone else with an Apple device to help you out.
Just wow. This can’t be legal by EU law.
call support and threaten them with bank chargebacks. They either will cancel you or you now can call your bank and tell them they won’t cancel you so you can do a chargeback. They will definitely cancel you after that.
report your Cc as stolen/lost and get a new one issued.
