I was told to post in this bug report forum by Game Master Feolaergue.
Every single payment method I have tried in the last 2-3 weeks keeps failing with an error message stating, please correct error with your payment method (no error being pointed out or made). I have tried 3 different cards with way more than enough available balance and nothing works. I have contacted my banks, and they said the problem is not on their end.
I have tried deleting the payment methods and retrying them, and still get the same message.
I did recently change my country location on my account from SE Asia to US, as I have recently moved back to the US. My SE Asian credit card has been working for payments. However, I would prefer not to use it anymore, for obvious reasons.
At this point, my subscription is ending soon, and I can’t renew it even if I tried at this point… since blizzard is not accepting any of my payment methods.
