Unacceptable Service

Good day, I purchased a vehicle on the 20th of December 2022 with a Dekra report of only one fault on the vehicle. The car started smoking within a month of purchase and I took it for a diagnostic upon the diagnostics being done the faults found on the car amounted to R106613.23 while I paid a cash price of R203850.00 I contacted the sales agent Unathi at the Springfield branch and he advised to log a concern through the website. I also contacted the webuycars contact centre several times for assistance and was advised to log on the website. I have logged a concern on the website on the 27th of January 2023 and the website clearly states that I will be contacted within 24 hours however I received no contact. I thereafter made contact with the sales agent Unathi to advise him I was not contacted through the formal process that I followed and he said he will advise them to provide feedback however I still have not received contact or any feedback from webuycars. Is this how webuycars treats me as a customer and who is going to liable for the costs and loss incurred on the purchase of my vehicle.
