I am getting tired of dealing with these yahoos

Today at 4:25PM Mr. Beckham from GM called. He immediately asked me why I didn't take my vehicle into Cable/Dahmer as he instructed me to do. I told him that I called Cable/Dahmer on Friday to make the appointment and to verify what he told me about the TSB before I drove the 150 mile round trip. I then said I was told that the TSB was for the transmission/engine software update and not for my radio/NAV unit or the electrical problems. I than told him that he as a customer service rep should have verified the TSB before he told me to go to the dealer. He then told me that he was merely relying on what the service manager at Cable/Dahmer had told him and that it wasn't his fault that the information was wrong. (This is the "District Specialist" for customer service) I once again told him he should have verified the information and asked him how a transmission software update would help me. I told him that my NAV unit rebooted once again on Friday and I want my vehicle fixed. He asked me to hold while he called the dealer. After about 3 or 4 minutes he got back on the line and told me the service manager was unavailable but he left a message for him to call him back. I asked him so what now? He then asked me to hold on and came back after a couple minutes. He then told me that he saw several other dealers in my area and perhaps a fresh set of eyes might find a solution. I told him that I doubt that it would and if Chevrolet had no fix for it what did he think another dealer might do. he then asked me if he could set another appointment up for 10/7/09 between 1:30PM and 3:30PM. I told him I will talk to him tomorrow then and hung up.
