John Williams motors bloemfontein

My name is Lindeleni Radebe-Memani I am very disappointed by john Williams motors Bloemfontein I bought b200 Mercedes Benz end of June 2022 its a demo care was having 5610 km now is at 19330km it means I only travelled 13720km. Last week I visited may family in KZN as I am currently staying in the eastern cape province, on route car indicated the tire problem then we stopped at the garage to fill up pressure as tire at the back was having low air then we continue when we reach kzn its indicated tire problem again and we decided to do proper check up and we found out that there is patch inside the tire and the line that is all over the tire inside. We decided to call john Williams seeking for assistant to my suprice the refused to assist saying that its not their problem its a factory fault maybe if it was a tire bust they can assist, desperately stranded with my family I decided to call my insurance upon their arrival they found out that all four tires are finished they need to be changed. When calling john williams management they refuse to assist and change the tires I don't know what to do now , I am sitting with this new car without tires paying lot of money, it means am going to sleep On the road with children because of poor service and unfair treatment I am correctly receiving, I don't understand if they are saying if it was a tire bust maybe they can assist they want me to die with my family because tire bust its life or death I wish I can take back this care and forget about Mercedes.

if anyone can assist me I can appreciate
