Myntra.com — refund wrongly processed

Last week i placed the return request of three items bought from myntra for which i had done the payment (Payment on delivery) via my debit card.

Now myntra has refunded amount to my myntra credit and refusing to credit it to my bank account (It was nowhere mentioned when i was placing the return request).

When i called them for this issue they are telling me to shop from myntra if i want to utilize this money. I have been bound to shop from myntra otherwise my money is blocked!!!

What a cheat is it!!!
