No Assistance from GWM SA

The worst customer service to assist with a vehicle that is at my premises (Turbo Panelbeaters) for 10 months and yes 10 months. NO parts no assistance to the GWM dealership to get the vehicle programed that was in a accident. A brand new GWM P300 with 300KM on the clock and this is the service one gets form a brand that preforms on sales but NOTHING when it gets to after sales assistance!!!!!!
