Brought car in for a recall. Was told it would take up to 2 hours to fix. Came back 2 1/2 hours later and it still wasn't done. Told them I would have to wait in the waiting room until it was done. After 6 hours I was told it has been done for an hour and was waiting on the paperwork. Told them I had been there waiting for 6 hours, they said they didn't know I was there waiting. I had checked on the progress 3 times while there. If not for being the only Chevrolet dealer in town I'd go elsewhere
