Paytm Mobile Solutions — Promo code scam

Address:	Bangalore, Karnataka, 560023
Website:	paytm.com

I did my first landline billpayment using newline and applied. Promode is accepted and went to the payment page. I have done the payment and received the message that refund will be done in 24hours after succesfull payment. Even after 24 hours of successful payment refund of promised refund didnt come. When i called the customer care they said that promocode not entered.
This has happened to me during first time bus booking by firstbus promo code.
Paytm is cheating people by showing the promocode, expect us to apply but actually it will not be registered. It may look like we have succesful in applying but its not. So be-careful. They are cheating.
