Hi i have booked bus from Bangalore to Hyderabad on 2oth of December 2017, and the travel date is 21st December 2017. I am supposed to board the bus at 10 PM at Madivala, i got a call from Mybus tickets saying that the bus has been cancelled. I was shocked as it's peak time (Holidays time) It's a long weekend.
They just say we are sorry the bus has been cancelled, no reasons said.
I have applied for leave on 21st i.e Friday, who is going to compensate for my leave ?
They are least bothered to provide an alternate to the customers.
How can they just say it's cancelled.
