I was overcharged for basic services. There was no communication about the length it would take to have my vehicle serviced. I made an appointment for 830am and sat for 2.5hours before I asked how much longer only to be told it would still be a few hours because the technician just started on my vehicle after 11am.my vehicle was not ready until after 1pm. Just overall poor customer service. My airbag light is on due to them repairing a recall on my vehicle.
