I call for oil change, 2 vehicles ahead, still waiting 55 minutes later. Slow, see staff walking around inside. Last time I come here, receptionist said about 30 minute wait, after waiting 15. Not impressed. Still waiting 1 hour and 5 minutes. Finally in after 1 hour 22 minutes wait, advisor was defensive of Receptionist. Not interested in listening to the Customer. complains about miss information. Was a frustrating experience, and just became negative to Summit GMC..
