I need urgently help. I am using the OpenAI api for an application that is used by hundreds of people. However, the second invoice is not being processed by OpenAi and it states that it failed. However my card works perfectly. I am also not able to update my payment options with other cards (Mastercard / Visa) as it states that it failed to update. I have read on discord that other users are also experiencing similar issues. Can someone help me here or how I can get hold of a support at OpenAI?
