BMW SA / Menlyn Auto Customer Service is shocking

In 2020 I bought a BMW 330i G20 from BMW Menlyn(Auto). Fantastic car and I have enjoyed it very much without issues with the car itself. I do however have an issue with how BMW SA and BMW Menlyn are treating me as their customer. When I went to collect the car I received the most mediocre of reveals ever. Firstly, The car was parked outside, no ribbon, no smoke, no gift. So I use to follow Menlyn Auto on Instagram and people who received their cars after me got big reveals with smoke and nice gifts. I emailed Menlyn auto, they ignored me. I then emailed BMW SA who said they will speak to Menlyn Auto about this. Menlyn Auto called me, a guy called Valentino Monaisa who said I should pick a date to collect a gift and a get a car wash, etc. I phoned him and gave him a date. A day before the date in question I called him and he gave me an excuse that his manager is currently on leave and he needs him to sign off. This was in June 2021. Until today Menlyn Auto have been ignoring me. I sent a follow up email to BMW SA, in turn they also ignored me. I guess because of the colour of my skin I am not an important customer to BMW despite buying a new car form them.
