Do not buy any part from Goldwagen

I Bought a thermostat housing from Goldwagen Humansdorp and the part was faulty, they clearly stated i have a warranty on the part, i took back the part for a refund than they start to seek excuses not to refund me. the Part cost R5200 and the manufacturer of the part needs to know that their parts is not been distributed by a credible company in south africa. Goldwagen do not want to refund me for the faulty part which is so so sad. please people stay far away from Goldwagen they do not look after their customers not giving service as they claim. stay away
