We Buy Cars bad service.

On the 8tt of March I took delivery of my car after a long and painfull experience. During the process, I had to contact the dealer for up dates. No response from the sales man nor F&I with regards to what was going on. Eventualy I got my car. It has been 6 weeks and still my car is not registered in my Name nor have I received the license and registration documents. Contacted the manager and he just say they have not received it yet and that his lic department is waiting for the Natis document. This is pethetic. I need help.
