I love this paytm services. They provide lots of discounts in recharge, d2h, online shopping and many more. Recently I purchased mosquito net that actual price is rs. 1042 but I got cash back of rs. 262.
I was very happy. Then I recharged my videocon d2h with amount rs. 609 and got cash back of rs. 100. But there is no such discount or cash back on airtel services. I think they also should provide discounts on Airtel. I would be very happy.
