They dont keep their word!!

I bought a Mini cooper S from Berea Motors Klerksdorp. The sun wisors were boken Wynand ask me to stop at BMW Klerksdorp ad order it on their account.., whitch I did. After 2 Months when I asked Rodney at BMW he said Wynand cancel the order and said Rodney must wait till he give him a order!!!! I also realised my car do not have a Nut lock, so I could not Change my tyres after hitting a pothole. I went to every tyre place in Klerksdorp, nobody could help me,also BMW, I phoned the owner of Berea Motors and he was very rude!!!!!! I a so disappointed!!!! Please do ot bye a car att Bera Motors Klerksdorp, your money is good enough but there is NO after sale service!!!
