1st - Paytm deducted balance and auto recharged my Prepaid number from my bank account without my consent. And it's near to impossible to get connected to their customer care. Whatif I wanted to recharge some other amounts! 2nd - Just like other loan apps, they take all your information and then never gives you any loan or anything. A way to take PAN and other personal information. 3rd - When my credit card was added/saved in the app, I used to get OTPs out of nowhere from Paytm.
