Gujarat State Road Transport Corporation [Gsrtc] — Amount dedicated but no ticket generated

Website:

gsrtc.in

The payment for the Volvo ticket booking was done and amount was deducted. After that one sms informing about successful payment was received but no PNR number and ticket were provided. If the status of transaction is checked on GSRTC then it shows successful. And at the same time when I check in history then the same transection is shown in failure list. So no resolution is available. If I am calling on customer care number then no customer executive is talking after waiting for 15 20 minutes on call. I have tried for more than 10 times to contact GSRTC customer care through their provided number, I did get failure all the time. How can I get my resolution and give me refund or ticket for my booking.
