BMW SMG DBN Service Department ... Sucks

My preferred BM dealer is SMG Dbn & the sales team have been super excellent, based on that i bought a few BM's from them over the years. On the other hand the service team have been "dropping the ball". There has been a few mishaps which i have overlooked because of the great relationship i enjoyed with some of the staff, however the latest incident has me fuming. My X3 was booked in twice in the last 6 months for service & none of the service agents informed me about a starter replacement. It was by chance i made an inqury about buying tyres another dealer when an agent informed me about my vehicle being listed on the recall campaign. The agent also offered to order & replace the item at a dealer who i met for the first time. It was so great to be kept informed & offered help by someone i enjoyed no history with, yet my regular dealer didnt bother to even update me. It seems like SMG DBN team are more focused on sales volumes & have little or no loyalty on servicing their regaulars
