I added a prepaid MasterCard to my Apple ID a while ago and apparently bought something with it. I don't know what this something is, but It's out of funds now and I can't pay my subscriptions anymore or buy anything new. This prepaid card is no longer valid, so I can't use it to pay. Is there a way to see what is unpaid, how do I pay it and remove this prepaid card so it doesn't cause further problems?
