Flipkart — Flipkart pay later account affecting Cibil report

In May, 2021, i checked my Cibil report and found there is a personal loan and 548 rupees is due on my name by IDFC first bank for which i never applied before. As well I don't have any type of intimation or information on mobile number or e-mail from idfc first bank. While I contacted IDFC bank it is reflecting because of paylater option available by Flipkart. However nothing is due to pay in flipkart paylater option and the proof for the same is attached. Then I contacted flipkart and they told me that nothing is due in my account and they will resolve the matter with IDFC bank in 2 days. And it's been 2 months and nothing is being resolved by flipkart. It affected my Cibil score by 150 points and in the future I have to apply for a home loan and I am worried about the same. Flipkart and IDFC bank are misusing the information of the customer and forwarding wrong information to credit rating agencies which is a big trouble for us.
