Paytm Mobile Solutions — frauding customers by opening paytm postpaid services without any request or approval

Hello,
Yesterday i tried recharging my dth using the paytm app, but since now paytm only accepts otp instead of 3d pin i was unable to access the otp so i decided to cancel the transaction but after few mins, i received an sms from paytm regarding the succesful transaction for recharge. Later when i checked my passbook the transaction was done using the paytm postpaid.
I never asked to activate the service.
Unfortunately, we can't even contact paytm we only have an option to write them a message which they don't reply in a proper manner. Also, i'm attending the screenshots of that chat.

For user
If you are using paytm and don't know about paytm postpaid kindly read the terms and condition properly, it is similar to your credit card if you don't pay it within a weeks time after a monthly cycle they start charging you interests for the same.
