Hotel premier O.R Tambo suite disgusting

I booked a suite while attending a business meeting at Premier hotel O.R Tambo. To my disgust the linen was not changed, the was no toilet paper in the toilet, the tea tray didn't have tea bags, the floors were not mopped, the bath and basin was not cleaned. I have never seen a hotel suite so dirty in my life, I have paid a lot of money for that suite and I was very disappointed.
