Century BMW

Needless to say that I was looking for a new car to replace my current one. So we did an internet search and found that this dealer had one that essentially matched our requirements. However, when we got there the next day, we were told that the particular car we looked at was already "SOLD", and wanted us to look at other cars ... this could potentially happen if we waited a few days in between, but that's not the case here. Ok, this could happen, small probability, but could, so I will give it some benefit of doubt. Then what happened next is just confusing. There was 3 people trying to "follow up" with me via emails and phone calls, until I made an appointment with one of them via email and got confirmation about the appointment. When I showed up at the dealership though, the sales person had no idea that I was coming that morning, and the car was not ready etc etc?. What's even more confusing is that I saw my name on their bulletin board for an appointment time that is entirely different than the one we reserved.
