Flipkart.com — No refund of Money even after 1 month

Address:

Tamil Nadu

Dear friends,
I purchased 2 John Players trousers for Rs.1160 (total bill value) from Flipkart.com on 11/jan/2013 (Order no: OD[protected]). Due to fitting issues, I returned back both the trousers & couried myself through The Professional Couriers (Tracking no: TVL2174566). It's almost 2 months going to over, still I didn't get my money refunded.
I have mailed them several times and spoke to Cust. Care executive but I get a same reply " in 2 days this will be solved". Please don't trust this site, as they are big cheaters. They acknowledge the items are received, but they are not refunding the amount.
