MakeMyTrip India — mmt denying my refund and committing fraud

I booked train tickets from make my trip and on the day of the journey on my way to station, I checked if the train was in the correct time, but to my surprise mmt app said that the train was cancelled. I called the customer service and also was told that the train was cancelled due to rains. I contacted the customer care through chat anfd the same was confirmed thatbthe train is cancelled and I’ll be getting my refund in few days. Now after almost 2 months mmt say that the train was not cancelled and the refund is not possible. This is fraud committed against me by mmt. I have proof about the cancellation. I had to spend another 5k through mmt again to book bus tickets to travel back as my train was cancelled.
