Flipkart — Closure of flipkart pay later account idfc bank

I request you to kindly deactivate / permanently close my flipkart pay later account.
When i see my credit score it is clearly showing that i took loan from idfc first bank and this needs to be cleared immediately as it is effecting my credit score. I have not used flipkart pay later from starting . I had requested customer care executive to close my pay later account and I also got mail from Flipkart that my issue will be resolved within 72 hours but it is more than 6 days than also my issue not resolved.So I request you to kindly deactivate my flipkart pay later account as soon as possible or I will take necessary action.
