Freecharge.in — Did not get cash back

Address:	Mumbai City, Maharashtra, 400092
Website:	www.freecharge.in

As per some McDonald's offer, we get 50 rs. coupon by voting in McD's website. We can utilize that coupon code by just doing one paid recharge/payment in FreeCharge. So we should get 50 rs more in FreeCharge's wallet. I Did transaction of 50rs from FreeCharge website (Transaction ID: FCVW[protected] ) and entered promocode QCHSQYYX3. It's been more than 2 days they haven't returned cash back in my account. When I mailed them about this issue, they send me some irrelevant reply saying that I already got and used that cash back and sent me some transaction IDs which are not there in my profile.
