First time I scheduled my car for a pontiac recall...

First time I scheduled my car for a pontiac recall for the airbags. I came in the day of my appointment, was told it would take 2 hours and they would call me when it was done. I didn't get a call, and when I called at the end of the day, I was told that my car hadn't even been moved because they didn't have the part and it would take a WEEK to get the part (even though I scheduled my appointment a week out, and told them what I was coming for). The service manager agreed to drive to drop my car to my house, and said that they would let me know when the part came in. A MONTH went by, no call or email. I called and was told I would get a call back with more info, no call back. So an additional notice of recall came in the mail, and this time I called the help phone number, after talking with this very nice lady, I was connected with a not-so-nice lady who worked at the location I had been to before who told me I had received calls and emails telling me the parts came in (which I hadn't, and I checked). Anyway, I scheduled another appointment, I came in and everyone I interacted with was rude (the first appointment day, a very respectful and courteous member of staff helped me). A couple of hours later I got my car back, but no multi point inspection check which I had signed for. I would never go back and I am trying to sell my car, because if they are the only place in my area who can service my car, I'll get a new one.
