BMW Sandton poor service

Ever since i bought my car in 2017 i have been taking it for service at BMW sandton, and on Monday when i took it for an assessment i discovered that the top cover of the engine is missing and this was the first time opening the bonet and i was not aware it was missing. i went to BMW sandton and spoke to Yolandi regarding the matter she told me she will look into the matter and until today she has not done anything and no communication from her side.

I am so dissappoited with the service im getting from this dealership.
