Paytm — Refund of bus ticket

Address:	Gautam Buddh Nagar, Uttar Pradesh
Website:	paytm.com

I have booked a bus ticket from chennai to bangalore via PAYTM to Roadlink Travels for 2nd October. But before 3 Hours there was a call from Roadlink travels about the Bus cancellation due to Breakdown, immediately i have made it to book tickets by directly contacting another bus operator.
When i applied for Refund to PAYTM, there was a reply stating that bus operator is denying about the cancellation hence bus ticket amount could not be refunded. But i have full proof about the call received from the bus operator and the SMS sent by the operator, till PAYTM is denying to make my payment. Will the customer again book tickets through PAYTM or suggest his friends to make it. Surely no system for PAYTM to be aware of the bus cancellation, there job ends once the bus ticket is booked. Hence be careful via booking with the third parties like PAYTM.
