Towing service doesn’t find motorcycle anymore

Last week we were with the motorcycle in the south of France. Unfortunately, when I was parked, I brushed a curb, which resulted in a leak in the oil tank. Fortunately, we made it to the next BMW motorcycle workshop. But there we were opened that one had only six or seven weeks for a repair. That was of course not an option for us. So we contacted the BMW-Pannendienst, whereupon the motorcycle allegedly slid off to another BMW workshop. Unfortunately it has not arrived there until today. The telephone demand at the address indicated by the towing service only led to the information that the dealer is a BMW dealer who only leads cars. Also no motorcycle has been delivered. At the BMW towing service we are comforted for more than a week, one will contact the local towing service to clarify the whereabouts of the motorcycle. This so far without success. We travelled back to Switzerland with a rental car. There is still no trace of the motorcycle. The fact that BMW apparently takes care of our problem with very little commitment is extremely frustrating.
