MBSA - Poor performance

My wife and myself have been a very satisfied Mercedes owners and drivers for over 20 years. Between us we owned 6 vehicles. About 6 months ago I had a bad experience which involved the fact that my vehicle did not have a spare wheel on board. The incident happened in a remote area, on a Sunday morning. I then decided to sell my beloved C200 and buy a car that does have a spare wheel. I then thought the least I could do is to communicate my point of view to MB SA and just get their side of the story as to why they decided to discontinue spare wheels for their vehicles, in South Africa. I sent a mail on 1 Oct 21 which I followed up with a mail directly to the CEO last week. Apart from an automated acknowledgement, I have yet to reply a proper reply. I certainly expected a better response from a company like MBSA.
