Flipkart — Pay Later mattrix

I ordered a product from flipkart using flipkart pay later. After that I paid that pay later due amount before the due date. My pay later limit is 500, I used 141 in it to buy one product. When I paid before the due date, flipkart charged me Rs 201. I paid 60 rupees more because I didn't want to spoil my CIBIL score.But after paying more than 60 rupees, I am being asked for money again and again and the claim is being made to suspend my account. I talked to the customer care of flipkart 4 to 5 times but they did not listen to me and disconnected my call. flipkart may have spoiled my cibil score b. My account is not suspended yet but I think this is not a good service of flipkart. I don't know what to do.
i have received the refund of rs.60 already.
but i want to know that did they spoiled my cibil score?
