Myntra.com — its 3 months and I have not received my refund yet

Address:

Hal, 3, 560017

I had cancelled 4 orders and they had to refund the amount to me. Each item was costing rs. 629/-. Therefore they had to refund the total amount of rs. 2516/-. They have refunded only 1258/- so far. I called their customer care multiple times and spoken to the supervisor also twice. I got an sms saying that my complaint has been registered, and after a week's time i got an sms that my complaint has been resolved. They have not resolved the complaint till now, as i have not got the refund nor the details of the bank transaction capturing the refund. They are pathetic in their service.
They had taken the return numbers from me.
