Zest Money — Incorrect loam amount overdue, affecting CIBIL Score

I took personal loan from zest money in 2021, for the tenure 1 year. The loan was in auto debit mode for few months and I closed it by paying the due before completion of the one year tenure. After everything got cleared up, my CIBIL score got messed up and upon enquiry, I came to know that there is one overdue payment of amount 2497 in zest money, where I have cleared all the loan amount and confirmed with customer care regarding the same. I could see it in Zestmoney app that I have cleared all the payment and that too early. Still my account has not been closed and it has affected my CIBIL score very badly.

I approached Zestmoney team over calls and requested followed by complaint but nothing they did to resolve. I followed them on the case with back to back mails, zest money team is giving responses saying that "we will resolve the issue, we will resolve the issue...please hold on...please hold on" and its affecting my CIBIL report badly for a long tenure by not addressing the situation. I am unable to get other loans due to bad CIBIL score. I hope my issue will get resolved here.
