BMW worst aftermarket service

I have a claim that has taken two months and not yet resolved. My bike went to BMW Desember for a noise the starter makes. The service adviser assured me it is a common problem with GS 1200 bikes and no need to worry about it going to leave me stranded. So I made a appointment in January to get it fixed under warranty. Could not make the appointment and hense thought on the next service lets do it all in one. Taking my bike back a couple of months after the warranty expired bmw only was willing to pay half the costs. I queried this and the matter was taken feom the dealer to customer care. Now here nothing happens. A month after the first contact still stories. Then I launched a complain. Suddenly there was a response. Now two months later still waiting. I cannot speak to a manager. I have to speak to my consultant. If I want to complain about the service I have to do it to the consultant I am complaining about. I drive a bmw car. Is on my second bmw bike. This is the worst service ever. If I ask the dealer they just refer me back to customer service. Is this standard practise for BMW? Giving the customers the runaround until they decide to hell with it. Let him go somewhere else?
