This is totally fraud app I have not received my cash back when I purchased Vivo V9 from Amazon through your App, whenever I call on your number I was always kept on hold for hour's but nobody came on line to get my problem solved. I thought that this is a Tata backed app & it will not cheat us, but I was wrong. You took me for a ride by taking Tata Brand name. Bhagwaan bachaye tumhare jaise chooron se.
