Had appointment scheduled for 11:40am to have tires mounted and balanced. Arrived early and waited in house for work to be completed. We’re told it would take an hour to hour and a half to be done(!) By 1:00, we received no notice of the work being completed. Went to service desk to inquire how much longer it would take. They had NOT EVEN STARTED, they were finishing up on another vehicle. No apology for the wait. Acted liked this was normal procedure. We drove 81 miles (161 miles RT) to have this service performed. We took our car and left. Wanted to warn others of the poor service.
