Redbus — Refuse to refund ticket amount when service is cancelled

Address:	560034
Website:	redbus.com

I have booked ticket in redbus portal on 4th may 2015, But the ticket got cancelled immediately(got the information through message and phone call). I am still having SMS undeleted in my phone.
so I informed redbus call center and they promised me that amount will be refunded in few days,

I waited patiently and even after repeated calls and followups no refund is issued.

It is very disturbing that my hard earned money which is supposed to be refunded is getting denied for no reason.

Even after customer service representative committing that it will be acted and I will be getting feedback or response with 48 hours,
still no one responded to me on this.

Multiple followups but no help.
