Poor GWM sales and service

Sent my GWM P300 for its 10 000km service. Booked it in a month in advance with instructions to fit a tow-bar (which was supposed to be included in the purchase agreement). After N1 city branch requesting ME to organise the parts to be transported from GWM Bruma to GWM N1 Ciy, Cape Town. The Tow-Bar was not fitted!
