Mobikwik — cancellation

We had actually booked a ticket from hyderabad to visakhapatnam. We had actually opted for a 10 o clock bus from boarding point ameerpet and we had made the payment. Later it said that it had started from ammerpet at 7 41 pm. But when we booked it showed that the bus is available at 10 clock at ameerpet. Now we called the bus operator and he told us that he wont refund the money and spoke rudely and not responded properly.

Travel date-26th sept
Operator-lta
Ticket pnr-ts[protected]ocdd
Operator pnr-10328
Seat no-36

We want a refund for this as we are not travelling by this bus and the options were inappropriate. When we tried to cancel the ticket, it didn't show the invoice details and says no invoice data. This is utter cheating. Hope you help us with this issue.
