It was raining the night before my appointment, so I wrote all my info on my own envelope, put my key in it and then placed it in your envelope & left my car in line. The next day when I hadn't heard from you, I then called the service dept and they said they had no record of my car or keys! It seems that b/c I didn't fill out the front of the envelope, in the rain, my envelope was just tossed on a desk & my car parked w/ nothing being done!!! That is totally irresponsible!. Obviously you had my keys & were able to move my car, so why no one looks to see why my name was on the books???? I was very disappointed with your service dept. I'm grateful they waved the oil change charge, but I had to ask & no offense, except for the secretary, no one in service seemed at all concerned!
