McKenna BMW

I would give 0 rating if I could, specifically because this is a BMW and I expect exceptional service from them. I bought my certified pre-owned BMW car from this dealer and it has been OVER 4 months that I have not received spare key for the car or the licence plates. I called up number of times and they keep promising in few weeks but that never happens. Really BMW? Do I have to follow up so much on such simple stuff? This is surely not the customer service I expected from a BMW dealer! Also, they were supposed to offer me a tire warranty when i bought the car. That is BMW policy as per another dealer. But they didnt offer any. I tried calling the finance dept to double check that and request more info on it, I left a voice mail and no one has called back till now. I ended up paying 400$ for changing my car rear tire instead of a 50$ deductible because of their shoddy paper work and screw up. I am never going to go back to this dealer or recommend anyone to them anymore.
