Poor Quality of Protea Marriot Hotels

I had to try drive from Pretoria to Durban on the 20th of December 2022 to attend a funeral. I left late afternoon and when it started to rain I decided to spend the night at the Montrose Protea Hotel at a cost of R1500. We did not request a paraplegic room but were given one . The room was not cleaned properly and the bathroom was the worst I have ever seen. The bathroom walls and floors were disgusting. Is this how Protea Marriot Hotels treats their paraplegic guests (does Protea Hotels assume that their paraplegic guests are all blind). I made bookings at Protea Hotel Karridene from 25 December and was tempted to cancel my booking. I must mention that the standard of Pretoria Marriot hotels has dropped significantly and not value for my hard earned money.
