Cred — No Refund- financial cheat

Hello there, I am writing this because of mental and financial torture I am facing because of this app called CRED. I have used this to pay my credit card bill on 4rth of sep 2022 money got deducted two times from my bank and it got credited to my credit card bill one time the other 2nd time money deducted (22300) is not been refunded till now. Neither I'm getting any proper response from customer support team till now. I'm suffering alot of problems due to this inconvenience and stucked money on CRED. I am not sure if they people have any intention to refund my money. I'm getting call from CSR team to just keep waiting and they are so unprofessional to another level keep asking my bank statement and hang up on me right after telling to keep waiting.
Also I got a fraud call two days ago on behalf on CRED i was in big risk.
Now I am being mental and financially tortured by this app CRED and it's staff.
What should I do?
