Purchased our vehicle from one of the Preferred Dealerships in GH. First oil change was free so scheduled for 6:20 Monday night. Not brought back to service until at least 6:40; by then a normal oil change shop would have had it done. Waited and waited and waited. Finally, at approximately 7:40 I told my husband I was going to find out what was taking so long. When I inquired at the counter, they couldn't find the paperwork or our keys immediately because they were so buried. Obviously they finished the vehicle, heaven knows when, but never bothered to inform us. Thank you so much for wasting my husband's and my night; shows a total disrespect for the customer.
