Bus root : chennai - tenkasi
Travel date : 2nd sep 2017
Booking date : 31st aug 2017
Cancellation date : 01st sep 2017

I have book three sheets in srm travels website using my credit card via paytm payment gateway. I have cancelled the ticket. But still am not received my amount back.

I have sent mail to [protected]@srmtransports.in and [protected]@srmtransports.in. But there is no response from srm travels.

I got the help desk number in srm travels website. When ever i call to that number call get forward to another number and call get ended.

Almost 13 days completed, there is no response from srm travels.

Worst customer service.
