MakeMyTrip India — Refund of cancelled Bus Ticket

M feeling very upset to book the ticket from make my trip. I had booked a bus ticket from patna to ranchi for 6th March. the bus was scheduled to depart at 8:30 pm and when i reached the bus stand and called the bus operator i was very surprised to know that the bus was cancelled for that night.for this i hadnt received any call from Make My trip nor the bus operator and in the middle of the night i was left no where to go and to my good luck i got a single ticket for the last bus from patna.The journey was not comfortable at all.
When I called the customer care of Make my trip everytime auto reply was on and call was getting disconnected.

Since the journey was not done on the booked bus hence pls return the ticket fare asap.
Had written mail on 8th but till now have got no revert either written or telephonic till date.
