Flipkart — Flipkart paylater bill discrepancy for the month of june

My total transactions done through Flipkart paylater for the month of june was for rs 6460. Out of which I had items cancelled and returned worth rs 4232. So the total purchase actually was rs 2228. I made a total payment of rs 4939 in the month of june. Out of which I should receive a refund of rs 2711. The amount has neither been credited to my account or the Flipkart paylater wallet. And the customer service people haven't given any information regarding the issue so far.
