Anew disappointing Hilton Hotel

I booked at Anew Hilton Hotel in Hilton Kzn, I was never told that the Hotel was busy with renovations, we paid and were given a room overlooking a building site, we had no choice to stay here as we had no time to look for other accommodation, if we new this we would of booked somewhere else before our trip.The bed mattress was terrible and was like sleeping in a canoe.
