I used to work at a BMW dealership as sales. but I never had this kind of experience. I mean we're not the only dealership in the bay area. and if I couldn't get a client to come in to close a deal, I'd do my best to see what their needs were, I wouldn't take my time to contact them and put them on "blast". That makes no sense especially since you've done business with him the current deal should have been easier.
