Freecharge.in — Cheated by not giving cash back

Address:

Paschim Medinipur, West Bengal

I do recharge my Tata docomo number +91 [protected] by Rs 150. At the time recharge promo code applied successfully but till date I am not getting my cashback of Rs 50. I also get mail which is mentioning that I will get Rs 50 as cashback. After several request the Freecharge representative are refusing to give the Cashback. This is a serious fraud which lead to consumer harrassment. Please help me to get the cashback as soon as possible.
