Tata Cliq — Cheating with customer

Address:	Bankura, West Bengal, 722203

Booked an power bank on flash sell offer. They have sent it through courier but i didn't receive it due to their own technical problems. I have the invoice copy of that. After a long struggle, they committed to offer me a coupon code with my money refund. I have repeatedly launched a complaint about the matter but they are not taking it seriously. Also there customer service is very poor. Still now i didn't get my money back to my bank account and also the coupon code. Please, i want a serious solution for that from you, so that i could get the booked order.
