It is a very good site for online recharge.and shopping .some times they give 100% cashback on online shopping and recharges .sometimes if there is problem with recharging, the customer care resolves it as soon as possible.we also get cashback on entertainment, food and travell charges.
But the only draw back on paytm is if any product cancelled it will takes 7-10 days to refund on wallet or bank. paytm always offered new offered and discounts .now you should book your tickets on irctc through paytm wallet .if you are a new user you will get 10-25 rs free recharge
