Cred Cash account still not closed in Credit report after 6 months

I availed a small loan from cred cash last year and then pre paid it before due date and it was settled. But the loan account was still reflecting as an IDFC first bank personal loan in my credit reports in the following months. I contacted cred grievance email id in April 2024 and they called me back the next day. I was asked for confirmation over the call if i still wanted to close my cred cash account, I said yes. They told me it would be closed and wouldn't reflect in your credit reports as active in few months. I know these processes takes time to reflect in credit reports. But still after 6 months the IDFC first bank loan account is still showing as active in my credit reports. My cred cash account was closed and it vanished from may or June. But now again cred cash is being shown in my cred account but as an offer to activate the account with higher loan limit. That means my cred cash account is closed but my personal account is not. Can someone guide me who to contact for all this? Cred or IDFC bank? Like if anyone can provide some email ids would be very grateful.
