Shoppersstop.com — Refund and Exchange pending for last two months

There are two complaints pending for last more than two months. I have made several calls as well as emails but no resolution till now.
I also requested for a supervisor but no one is connecting or arranging a call back . Today again I called and was about to request for a supervisor but agent hung up on me. Worst Customer Service !
Here is the complaint number for both cases.
