Ducati SA bad business practices

i have been trying to get Ducati to honour there sale agreement i have had nothing but rudeness since making my payment i am still waiting for the roadworthy certificate and the owners manual i can only assume that the vehicle was defective and that they had mislead me into thinking that it was in good order and roadworthy and that it had aĺl the nessessary documents . i am teribly disappointed with the attitude after they recieved the payment clearly this isnt good for people who are running this global brand in south Africa we bought this vehicle online during the lockdown we recieved it unserviced that had to be done locally then after it was serviced which they eventually paid for, the bike was tested by us the rider was injured as a result of eratic throttle response and has been hospitalised i futher went to register the vehicle only to find that there had been no roadworthy certificate issued . the general manager confirmed that it had no roadworthy done and as far as he was concerned that was the end of the matter . i reminded him that i had been sent documents by his sales people stating that the roadworthy and all documents were in order. which i am still waiting for and told him if i had known that it was not the case i certainly wouldn't have purched it . to date i have received no further response i suspect that i will have to persue this through my legal representative. i did say that i had purchased in good faith and a price and terms were agreed of which i have fulfilled my side, the service workshop has done what they were asked, to date Ducati haven't fulfilled there side of the transaction as it means absolutely nothing to Ducati to keep their side of the agreement it seems. this is will be terribly damaging to Ducati.
