Autobahn BMW - BAD SERVICE

A very disappointing experience with Autobahn BMW Isando. Took my vehicle in months ago and a small cash note amount was ****** out of visor. I realise this is my responsibility to remove all valuables but certainly an unacceptable behaviour from such a supposedly prestigious automobile brand. Took vehicle in again last week - AND AGAIN money notes ****** from visor. I have left 2 messages with the Branch for a Manager to call me - just to bring this to their attention - TO DATE NOT A SINGLE CALL BACK. On the day of the service a consultant called me to ask whether I was happy with my vehicle. The vehicle was still in for service - why would she ask such a question, if they had my vehicle in the workshop. Why is the system so confused ? I received a call 6 days later (today) asking again if I was happy with my service, but still no return call from the Branch. The consultant was quick to ask whether I would be in the market to purchase a new vehicle - perhaps they need to resolve old issues, before asking that question.
