Atrocious Service InspectaCar CitySide

I am disgusted with the absolute poor Client relations experienced whilst dealing with InspectaCar Cityside in Arcadia. After purchasing a BMW X5 from them in July 2020, (cash purchase) I have had endless issues with Latent Defects on the vehicle which has cost close on to R100k in getting resolved. When I approached the dealership regarding the matter, they basically told me that they had to speak to their vehicle supplier regarding the situation to see if they could recover any funds from the third party before they could offer me any compensation. This has now dragged on for more than 2 weeks. To top that, I had to waot 7 months to get my NATIS documents from them. I have yet to receive the License Disc as they can not provide a valid roadworthy certificate. This after forking out R2500 for the dealership to have this done. I am at wits end as I am having mo joy in resolving the issues with the Management of the said dealership. Next step would be to approach the the MIO to intervene.
