ChatGPT payment has been declining all cards for the past week — bank confirmed no issues on their end

Welcome to the Dev Community, @mongg! Thanks for detailing everything you’ve already tried, especially testing multiple cards, checking with your banks, and trying across different devices. That definitely sounds more extensive than the usual browser or cache-related issues. If you’ve already contacted OpenAI Support and have a case ID, could you share it here so I can reference it internally? If not, please create a support ticket through the Help Center and share the case ID once you receive it. ~Smith
