GWM SA useless!

I have ordered a part from GWM Westrand, 139 Ontdekkers Road, Roodepoort, more than 7 weeks ago! Delivery would take a maximum of four weeks! The promises from the dealer AND GWN SA keep on coming but NO PART is anywhere on the horison! I WOULD SUGGEST THAT NO-ONE purchase a GWM/Haval/Mahindra as their after sales service does not exist!
