Ok sometimes we can trust it but in recharges paytm is not updated with all the offers, some offers were not updated. In begining paytm offers were more but gradually they decreased the cash back offers. I feel that initial stages they want customers not they are sufficient.
In an positive way we can sit and order any thing online, which saves our time. For first time users they offer some offers but it wont work. I dont know whats the reason behind it.
