I used the PayTm app for recharging & for online shopping the product. First Thing the products are not really a branded one and they take huge time to delivery the product.
Some times well forgot about the product. Some times if cancelled the order the amount will not be transfer to my account it will directly go to the PayTm account. Anyway again you should use that amount onlyin PayTm. For recharge also there are doing the same & most of the time rechare will not be success.
