I experienced same for my regularly scheduled VPN card debit. Contacted Bangkok bank help # listed on their site. Explained the situation and affirmed to them that it was a authorized charge by me. They asked me for how long and I said indefinitely, and they said they would resolve the issue right away. I held the phone for several minutes, they came back, the situation was resolved. Re-subscribe to my VPN provider with no payment issue.
