Bus delayed & nobrefund ticket fare

I had booked a bus ticket with Sri Sugam Travels (through Red Bus) for travel from Hosur to Vellore, scheduled at 1:45 am on 25th October. I reached the Hosur boarding point by 1:30 am as instructed, well before the departure time. The bus did not arrive on time and was delayed without any prior information. Despite waiting at the boarding point, I was not able to travel as per the scheduled service. I have not received any refund for this service failure. I request Red Bus and Sri Sugam Travels to refund the full ticket amount paid by me for this trip.
