I always use Paytm for paying my mobile bills.
This website give best cashback and discounts than other websites or wallets.
Also website is superbly designed.
Specially Nett Price to be paid is very well described.
There are no hidden charges.
Only packing quality is not so well of delivered product.
Please use paytm for best cashback offer.
Every online website has offers that say 50 off or more and price of all the products is similar in all website almost everytime. but paytm is different . The cashback we get is the real discounted amount.
