Redbus is Didnt get any response from red bus, it has been more than 12 days

Booked a ticket of 24 june (23:45) from redbus, and the bus was delayed by 1:15 hrs,
After that delay message.. no further information about bus was provide by either red bus or by the travel operater.. they didnt responded the phone calls. Unfortunately i had to book another ticket from red bus at 2.00AM..
I filed a complaint with red bus next day for the refund of previous ticket, but no refund has yet been made and whenever i call the redbus regarding refund, i just get a reply that you case has been tranfered to seniors, they will call you withing 24 bours..
Its has been more than 12 days.. no resolution given yet..
