Disgusted & Disappointed in the BMW Brand

I really don't understand, a brand that has this reputation, to disappoint your end user, going through all this frustrating dealings, And my vehicle is still within the manufacturing warranty, I bought my BMW in DEC `17, like any other person you do your research before purchasing a vehicle to sooth your needs, First, my vehicle started to lose water, I had to fill water every morning and afternoon, starting issues, and started smoking, so bear in mind I only drove this car from mid DEC `17 and started to have issue in mid Mar `18 , contacted BMW to not willing to assist , The dealer I purchased the vehicle from pushes the problem to BMW , and BMW to the dealer (Cittons Cars PTA) , then I decided to take the vehicle to JSN Bryanston , as recommended by Citton Cars Sales person, (Deon Moolman) , JSN BMW , I explained the seriousness of the issues I have but still told me I have to wait 2 weeks for an opening, so I said fine I’ll wait , this booking lady still hold me if anything happens in the meantime just call BMW ON CALL , I mean really, Ok so my vehicle went in they replace some clamps that was faulty kept the car for a day return it to me the following day, Just to find my car has been damage on the passenger door and my money is missing from the center compartment, And within days my vehicle has the same problems, Now I am sitting: 1. With a damaged vehicle 2. With a vehicles that us overheating still 3. JSN BMW only replying to me a week later only to tell about to run a diagnosis, but say nothing about my damages I am utterly disgusted with BMW Brand,
