Incompetence of the highest order

Paid R1500 for a pair of cv joints. The incorrect part was sent to me aleven after i uploaded my vin and engine number to tgeor website. The box itself says its for a 1.4 polo but the woman assisting me insists it is for a golf 5 gti. My car was supposed to have been fixed on Saturday (07.09.2024) but it is still lying at my mechanic because oof this incompetance and i cannot go to work!!!
