Pepperfry - Pepperfry not refunded my amount back

I had purchased a product worth around ***** in pepperfry and cancelled as it was not required. I was expecting refund in bank account as Amazon kind of ecommerce send refund to Bank account. Pepperfry had put the money in pepperfry wallet which i am not aware. I made a small purchase to check if I can use that wallet amount. So i utilised *** rupees out of *****. I then enquired if I can get the available balance in wallet to my bank account. They agreed initially but upon checking during transfer they said since you have utilised *** rupees we cannot transfer any amount back. So this means i can only utilise the amount for pepperfry purchases now. They are claiming that i since I had utilised partial amount, turning the blame on my end they are unable to refund. No consumer will be aware about these internal rules of pepperfry. This is system issue from their end for which consumer must not be affected.
