Dirty room and bad service

My husband and are are from the USA. I am native South African and it's my husband's first visit to South Africa, Cape Town. We booked in for only one night at the Lagoon Beach Hotel in Milnerton. When we got to the room, the room was dirty, the bath tub was dirty and I found some one else's razor left in the shower. I called reception/housekeeping and asked for us to be move to another room... I was told that the hotel was fully booked but they will send someone upstairs to clean. We then left the room and went out for dinner. When we got back - the room was still not cleaned. I called reception/housekeeping again and they sent some one up only to bring me towels and water and no cleaning of the room done. I am so disappointed as this was our one night in Cape Town and I expected much better. There was no apology, no redemption or anything that made me feel like I was a valued client. I am in shock and I feel saddened that my husband's first experience at a hotel in Cape Town was this disgusting. We will NEVER visit this hotel again or recommend it to any of our friends or family.
