Booking.com complaint: Not accepting to cancel a reservation

I made a reservation for hotel. after that and during checking My ation, I found out it isn’t the same hotel which I want to make reservation for! I tried to mange this reservation from the email they have sent to me and their link doesn’t open! I have called them several times to get the cancellation and they saying they are helping for that but the matter of fact is not helping, they just making me going through long process and wasting my time and of course not cancel that reservation and not refunding money. I didn’t make not cancel reservation and I didn’t make not refundable reservation which they were telling me later after making me calling their calling center and made me going through long process!!! What is service that not cancel reservation under any circumstances especially not making not canceled reservation or not refundable reservation!!!!!
