None Existent Customer Care

We purchased a Hyundai Exeter - Plumstead branch end July 2025, cash. This was our daughter's 21st present. Still waiting for the car licence, registration documents and number plates. My husband has contacted the sales rep - no reply, the new car sales manager - no reply. The Dealer Principal - no reply. We have tried to send emails to their i care address - no answer. Linked message to the customer care - no answer. Sent messages on their automated customer care system - no answer. How do you get hold of anyone to deal with this problem! You have exactly, 2 days to contact us otherwise I will be contacting your overseas Head Office to notify them how customers are treated in Soutth Africa.
