Flipkart — Cibil Affected

Im using paylater service of Flipkart from 2021 onwards. And i was not having any overdues i paid all the payments on the right time but last month i have noticed that in my cibil record few payments are in due . When i contacted the bank they informed me that flipkart has not transferred the money to bank that i paid in flipkart so that a due amount of 4860. And this has affected my cibil report badly then I raised a complaint in the flipkart help desk on Dec 3rd, they were simply handling the issue with out solving the issue, till now im facing this issue .
