Personally haven't faced any problems with paytm as such.. Instead it has proved a kind of a savior here in Bangalore during this cash shortage period with every vegetable/small grocery shops etc. accepting paytm transactions..
But I don't like the way they advertise cash back offers.. 100% cashback should not be the main title if the max cashback amount is as low as Rs5/Rs10.. I recharge my d2h every month and use some random coupons which advertise huge percentage of cashbacks but finally I end up getting Rs2/Rs3 cashback.. So I have even stopped checking the details and just go with whatever is offered

I find Freecharge is far better comparatively, they clearly mention Rs50 cashback on bescom bill payments and also give the same immediately..
