Srm Transports — bus delayed by 2:30 hrs without any intimation

Hi,
I had booked the bus to kumbakonam from chennai on friday (10th aug). The boarding point was at shanthi petrol pump near airport and the pickup time mentioned as 11:00pm. I was waiting at the pickup point from 10 :40. Pm till 1:00 pm but there was no sign of the bus. The customer call center number was not responding and there was no intimation. I eventually left the pickup location at 1:00 am and came back home. I received a call from the driver at around 1:30 pm that he had reached the pickup location but was unable to reach there as i was near home.

Requesting a refund of the amount paid for the ticket (Rs 1100) as i have missed the bus due to negligence of srm transport.

Regards,
Pratap
