Failed bus booking
Upi ref no[protected]
Time - 9:57 pm

I try to book a ticket through msrtc portal, using phone pay upi id, the payment was successful but the booking failed, i got 50 rs cashback aslo in phone pay wallet, but i want refund my rs. 371

I used my vertual payment address for payment process, then i get a request msg on phone pay, i accept that request, the money got deducted but the payment page doesn't go any further, and does not show any successful msg,. After 10-15 min the msrtc page goes to home page and it displays that the booking was unsuccessful, but rs.371 was deducted frm my bank account on 3 feb 2018.
Pl give me refund.

Thanks.
