Plus membership fee got refunded but ChatGPTPlus still works

Hi.
I made a subscription with email id: shaileshrana77@yahoo.com on March 20,2023 (IST)
Some of the amount of the subscription was refunded but the Plus membership still works.
My card details and address isn’t visible in profile section and when I add any card, it shows: Your Card is Declined.
I don’t want my membership to stop working after the month ends, it’s part of my workflow now.
Also, Chat option isn’t working for me.
