I have access to the Upgrade Plan option on the ChatGPT interface, but I am located in France and am having trouble upgrading my account to ChatGPT Plus on the pay.openai page. I am unable to select a country other than the United States for the delivery address, and I've encountered issues with multiple credit and debit cards.
Error messages I have received include:
"Your credit card has been declined. Please try paying with a debit card."
"Your card has been declined. Please try paying with another card."
I have tried accessing the Upgrade Plan option on the ChatGPT interface from multiple browsers, IP addresses, and even from my phone, i still have the same issue.
