Ibibo Group / Goibibo — hotel cancellation refund. no status

I've booked hotel room for 2 nights in amritsar in october. When i reached amritsar we have received call from hotel that we cannot provide you the room since there are some issues in room. We can provide you the other hotel room and will cancel the booking and will refund within 3 working days.
From that time i am coordinating with goibibo for refund but there is no reply.
There executive said that we will refund the amount. I received email that we will process the refund within 15 days. No amount received yet.
