Without warning, OpenAI downgraded my subscription from Pro to Free

Hello again, The response from OpenAI has become absurd. Customer service denies having canceled my subscription, but now claims that there were problems with payment that caused my subscription to be canceled. I have an email from that documents that OpenAI refunded the payment after claiming that I had requested that the subscription be canceled - which is not true. Attached is the receipt that documents that I had paid for the pro subscription on May 20, 2026. The email from OpenAI informing me of the cancellation and refund, documents, together with the receipt that I had paid for the Pro subscription on May 20, 2026, that it is OpenAI that has canceled my subscription manually, and that it is not due to a lack of payment on my part. Could you please clear this up? Thanks in advance Regards Sveinung
