Went to the Mentor Mitsubishi building, doors were locked and no signs as to why. Called and said they are now at the Kia building. Arrived at the Kia building and no signs as to where to go for Mitsubishi service. Finally found the service desk, and was told that my appointment was not in the system. I had booked an appointment online, even showed a printout of the appointment confirmation. Thankfully, they were able to fit me in and service was completed to my satisfaction. Also was hard to find parking. I'm satisfied with the service, but improvements are needed in online booking, as well as signage for customers.
