I have never had such a poor 5* experience before

I am well accustomed with 5 star establishments both locally and internationally, and have never had such an unsatisfying experience before.Radisson Blu Sandton is firstly very shabby when compared to other near by 5*'s....from the parking lot which somewhat reminds me of a dingy hospital car park.(Had I of chosen to use one of my personal vehicles instead of a company one),I would of had a serious issue parking my vehicle there...and at an additional rate of R40 per night.From my first interaction with their reception-I was completely put off as she did not even have the courtesy to advise on how the elevators and card systems work,not offered to call a porter for us.I checked in on 27/06 until 29th....on the 1st 2 mornings I actually chose not eat breakfast as their '1' toaster was not working and I simply do not eat breakfast without toast. The worst was the level of hygiene-after my room had been turned over..... I noted the shower was not cleaned(full marks and grub on shower doors and floors)
