Terrible service

Absolutely terrible turn around time in there service department. I brought my car in the 6th of March 2017 and still today a week and a half later I'm sitting without a vehicle. I was not even issued a loan car. When I try and follow up with what's going on all feedback I get is we waiting for the Warrenty agreement and service history. Now nearly 2 weeks later I get told it's my responsibility to bring them this documentation because BMW won't release the information to 3rd party members. This would have been resolved a lot sooner if I was told from the beginning they needed this information. Won't suggest this company what's so ever and won't purchase another vehicle from them either.
