recall service failure, unresponsive staff

Full record text

vehicle recall. Dropped the vehicle on a Thursday, was not offered a loner car. My truck sat at the dealership until Monday. On Monday I called the dealer 3 times and left messages each time for the service advisor. Also one message for the service manager. I did not receive any response from either. I went to the dealership on Monday afternoon and spoke with the service advisor who stated he did not receive any messages from me. I asked to see the service manger and was told he was busy. I than asked the status of my vehicle. I was told they could not find the reason I was losing coolant and could not do the recall because they did not have the part. I never received a phone call telling me my truck was ready to be picked up. They also had made the appointment for the recall and they did not have the part in stock to do this when the appointment was made. This is not the first time this has happened to me at this dealership. Upon doing research I found this engine on my truck is know to leak coolant into the cylinders.
