Mercedes-Benz of Westmont

Made an annual service appointment on my Mercedes Benz. The actual service/maintenance performed on my vehicle was fine but service through advisor was a big disappointment such that I won't be purchasing a Mercedes again from this dealership. This is based on last year's annual service appointment and this year's annual service appointment. I brought my car in for service at 10:00 AM and unfortunately, the service department no longer uses porters but Uber. My advisor contacted Uber to take me back home. I got in the Uber vehicle and the driver told me the address that he was driving me to. I told him that wasn't correct and he assumed I made the call for pick up. The Uber driver told me that he couldn't take me to my home address because that wasn't the address he received. I had to go back into the service area and find my advisor and explain the situation to him. He checked his records and my address was correct in their system so he couldn't understand why Uber had the wrong address. My service advisor had to come out and explain the situation to the Uber driver. It ended up that the driver had to change the address on his phone in order that he could take me home. That day I waited at home for Mercedes to call me and inform me that my car was ready. I waited and waited, and finally I called at 5:30 PM since no one had called me. I called my advisor's line but he most likely left for the day. I called back and was told my car was ready and that I could come and pick it up. The individual I talked to was ready to hang up the phone and I said how do you expect me to get to your dealership, walk. She then stated she would need to talk to her manager. She said her manager would call Uber to pick me up. I told her forget it after my experience in the morning with the wrong address, I wasn't going to wait outside for someone who would never show up. Given it was almost 6:00 pm and the dealership/service area would be closing in an hour, I told them that I would ask a friend to drive me to their dealership tomorrow so that I could get my car. Now, this is what happened at last year's service appointment which resulted in me waiting outside in the rain 45 minutes. I received a call around 5:30 pm that a porter was coming to pick me up so that I could get my car. The porter was delayed from a previous pick up but no one called me to notify me of the delay. I waited in my condo vestibule about 15 minutes but no one showed up. I thought because of the rain and it was evening, the porter couldn't find my building so I walked in the rain to the entrance of my complex and took cover under an awning. After almost waiting 30 minutes,, I called the service department. The phones just rang and rang with no one picking up the phone. I called back several times and each time pushed another designated number to speak to someone. Finally, after my 4th time calling, I spoke to the operator who transferred me. The person who then answered apologized and told me that they were experiencing a problem and the porter is coming now to pick me up. I told him I sure hope so because the dealership would be closing in about 40 minutes. As for some of the survey questions, I truly can't answer "yes" or "no." For instance, did the dealer honor all commitments made? I would think calling me to notify me that my car is ready for pick up would be a commitment though the advisor never said that he would call me. Also, I'm not sure whether the work was completed within the timeframe promised, since I never received a called when my car was ready for pick up. Yes, I could have called back after the promised time but based on my previous experience when I brought my car in for service and I did call back at my promised time I would find my car wasn't ready, or the mechanic found something additional that needed to be repaired so my service advisor would need to call me back anyway.
