IDFC Bank — Wrong data send by bank to cibil

Address:

Modinagar

I have a flipkart pay later account powered by idfc fisrt bank from 2019.
My account number is 27668384.
I have not used any limit on may 2021 but from may 2021, my cibil report shows that their is some outstanding amount on your idfc fisrt bank account and this continued for 5 month. My credit score goes very down without my any fault. I contact to the cibil department for this error, they said that this reports is sended by the bank. I contact to flipkart but flipkart employee said that your account has all clear and no outstanding amount then, I contact to idfc customer care and same they said that no outstanding amount on your account.
Then i check on different cibil score sites like cibil, experian, equifax etc. but they all shown the same. And now without my any concent, idfc bank closes the loan last month with a status - suit filed, written off.
I want to immediately correct my all previous months report by the bank and report it to all credit score departments and change the account status to be closed without any errors.
