Hi Nathan0809, thanks for joining the Community - this error means that the payment authorisation failed; please either use a different payment card or contact your bank provider to understand why the funds are not being relinquished.
Im not trying to pay my subscription i just wanted to switch to a new bank card as my current card expires at the end of this month, how will i get my new card updated to pay for the month of October?
We don't want you to have this situation while updating the billing information, @Nathan0809. I'd like to give you some more information so you can completely add the new bank account.
I agree with GeorgiaC that the error indicates a failed payment authorisation. I advise using a new credit card or contacting your financial institution to find out why the problem occurred.
If your bank verifies that there's no issue on their end, it's best to get in touch with our Customer Care Support. This way, they can look into this further and give you the best resolution to your concern.
