Paytm is very usefull and very effective app, by using single app you can perform muti operation like, mobile recharch, ticket booking any kind kind of bill payment but its offer are very fake and given promiss not full fill. I am sharing my one experience jan. 2017 they are offering 100% cash back on purchasing petrol by using paytm but till date I have not received my cashback. For the proof I am attaching sceenshot of that offer with my paytm pasbook kindly find and after that incident still I am not using this app.
