So I've been trying to pay my sub with a different card after a long hiatus but the common
"The system was unable to update your billing information. Please verify your billing information and try again later. If you continue to experience this error, you may wish to try another credit card or contact your issuing bank. To request further assistance, please visit support.turbine.com. [err: 30005] "
Issue has been cropping up, as I'm not in the US, I refuse to make international calls to sort this out, and no, predictably, I don't own a fax machine or feel comfortable faxing payment details. I've tried two different cards and I know there's nothing wrong with the details I'm entering.
How does one actually pay for this game?
