Toyota Vredendal no customer care and aftersales service

I bought a Hilux Legend 45 from Vredendal Toyota. On 45000km tje motor packed up. They took the whole December to repair. On 50000km it packed up again. Again they had to repair it. On the new motor I have been waiting 3 months now for them to stamp a new enjin number. They also fitted windshields (original Toyota spares). These things started to come off. The Vredendal Toyota workshop team broke one - promised me they are ordering new ones. 3 months nothing. Whatbis worse is there is no feedback from them. Everytome I contact them they promise to come back to me, or the windshields is on backorder... But no joy. Extremely bad after sales service. No communication, no customer care. I emailed the complaint to Toyota SA customer care... No result.
