My experience was good with the paytm. I pay my mobile bills usually with paytm. It was a good experience so far. I have done shopping also like jeans, goggles . The quality was good for products, prices ware cheap as compared to product quality and the cashback thing is so awasome! sometimes there serves are down.but customer service do good with that.
I will surely recommend my frnds and family to use paytm!
Cheers!
