BMW Pathetic service

<p>BMW aftersale service is pathetic. I am so disappointed in BMW I can not express myself. I forwarded a compliant even the complaint service is not assisting.BMW did not change oil during a service after an average of 20 000km interval and now my car has a sludge they say no they only changed brakes then and I drove car over service. I thought no the car just went for a service it can't be minus owing a service again.I am going toToyotacoz they know it's common sense after so much KM a major service must be done. Never BMW and key reader nonsense. </p>
