Registration papers not provided for vehicle purchased on auction

I bought a car on auction from them on Saturday 2 November 2024, which was supposed to have papers. I paid for it within 24 hours and picked it up during the week as required. The papers were supposed to be sent to me via courier. To date I have not received the papers with promises that it will be sent. This is unacceptable since I can’t register the car nor use it. I have had two parties interested in buying the car since I got it bad could not sell due the registration not being available. I wil not do business with these auctioneers in future.
