Myntra.com — they are not refunding my entire amount

I paid 252rs online for purchased shoes from myntra. They cancelled all my two orders. As committed by them they refunded my amount. But they transferred only 200rs. 52rs still had to be paid by them. Reason unknown. They are cheating with customers by giving them loot offers. Government should have to take serious actions against these kind of sites. I hope i get justice.
