PAthetic Dealership - Haval Tollgate!

The fist time i booked my vehicle in for a service, i get no call from a service advisor only to get to the dealership and it was closed. Upon them opening up and receving the vehicle the setup for my GPS was changed to Apple when i called them to resolve i was told they do not have the the machine to reset and the will need to borrow it from another dealership. Today i take it back for a regular oil change, nobody calls me. i call 3 times nobody returns my call.@ 16:30 i call back and they mention the vehicle is not ready. This has to be the most untidy workshop and the most unprofessional dealership i have dealt with. *****DO NOT PURCHASE A VEHICLE FROM GWM TOLL GATE***** all the calls to them were recorded . They also refuse to tell me who is the dealer principle!
