Poor service

Feedback on an extremely frustrating experience. Mercedes Benz Constantia usually extremely efficient, never had a bad experience prior to this one. Vehicle was booked for service (19/11/21). Check in fantastic, very quick and seemless. The Collection on the other hand. Total disaster! Service advisor says to be there at 4:30pm. At the time of writing this it post, it was 5:20pm. + 50 minutes wait. Now waiting is OK, but almost an hour and still the vehicle was not ready. Compounding the disaster is that there is no communication. We'll at least not until I asked. 1 Hour later. Should I go and ask again because doesn't seem like anybody seems to feel the need to keep me updated. It would appear that making me wait, I should consider a privilege, to be stalled in a Mercedes Benz reception. Never mind COVID 19 and the hoards of people passing by me. An hour and not even the courtesy of a glass of water? I was always of the impression that Mercedes Benz was a customer centric organization. Guess I was wrong! Proceeded to post on a message to them on Facebook, 4 business days, 6 in total and no response. It would appear that there is a theme. It's simple really, customer satisfaction is not a priority. In fact, I would be surprised if this gets a response. You may ask, why I'm I still on about this. It's simple, I expect premium service from a premium brand. Red flags are raised when a customer is not treated with the dillegence and respect they deserve. Service like this must be highlighted and rectified! Due apologies my be given. But again, I don't expect anything. Given my experience, Mercedes just went from Hero to Zero!
