Booking.com complaint: Failure to credit charges

I made a reservation for a hotel with an indoor pool to treat my grandkids. After contacting the hotel, I found out their pool was not in use. I contacted Booking.com, who said I would have to request with the property to cancel, which I did. Booking.com then said they couldn’t credit my charges until they heard from the property. I called the property, they told me it was cancelled. I called back to Booking.com, they said they talked to the property and ed it was cancelled, but they would need written approval. I received an email from the property saying the reservation was cancelled. I called booking.com three times before my reservation date, always being told they had to wait for written ation. I contacted the property about three days before my reservation date. They verbally ed that the reservation was cancelled and that they had responded to booking.com. It has now been over one month, and three more calls to booking.com get me nowhere. The say they are waiting for a written ation from the property.
