Ibibo Group / Goibibo — hotel booking cancelled

I had made a hotel booking for a nights stay at kochi mermaid hotel. The booking was confirmed by goibibo via email and whatsapp mesaages. The payment mode confirmed was to pay at hotel and hence no advance payments were made. Upon reaching the destination, i was denied checkin with a reason that i did not make advance payment. I contacted the customer support of ho ibibo via chat and they made we wait like hlf hour and still there was no response. Adding to the woes my gocash points was also utilised by goibibo against this booking and it means i loss that also with no use. Its a financial loss as well as mental stress that i had to go through just because i booked through goibibo. I demand a proper response and return of my go cash as well.
