Terrible service. I waited to be helped for 10 minutes. I was then told to wait by my car, where I waited another 20 minutes. Finally, someone came over to help out. I waited a little more so my advisor for this trip could finish with another client (which is not a problem), then he came to help. I had told them I still needed to grab stuff out of my car and put it in the loaner vehicle. He assured me it would still be there after I finished checking the loaner out. Lo and behold, the car was gone after I checked the loaner out.
After nearly and hour, I finally got out of there. Mind you, I was only there to get some winter tires/wheels put on. I might as well go to discount from now on. I am thoroughly disappointed and I m not sure what happened to their service department. It used to be that the client was their number one priority, but it seems that this is simply not the case. How sad.
