Momentum Volkswagen

I got a great deal on a VW GTI but they were missing a keyless remote for the car. I was told it should take approximately a week or two. I called back a month later and was told to come in to get it. I came in and was told they couldn't find it and needed to order another one. I came in again and they said I needed to program it but that the programmer was gone for the day. Really, I don't like to think of myself as an impatient person but I live approximately 30 minutes away. How can these people be so inconsiderate? I'm not looking for any freebies. I would like only what they offered me to begin with.
