Ford Lazarus Centurion faulty cars

Hi, I've bought a car from Ford Lazarus Centurion in February 2020 with 63000km on the clock. Took the car in today for its annual service with 70000km on the clock. Now the company wants to replace my Front discs as they have hotspots on them, and my front break pads and wipers. while the car was only driven 7000km, This was mainly trips to school and some times to Midrand. This makes me very concerned as this should have been picked up a year back when i bought the car with the initial inspection. Break discs should last on average 110000km and break pads 64000km. This is unacceptable and i can not be responsible for this as there was no mention of this that i should do it within the next 7000km. When spoken to the branch i spoke to Chris the main guy in the workshop and just said there is nothing he can do, that is unfortunately my fight with them because it is a different department. which i understand, but it is still the same company. And better customer service would have been, sir, ill find out and sort it out. not, come see me or ill find out if a Chantelle still works here who sold the car to you. In the meantime, i phoned Chantelle and were informed she is on another call and left a message to phone me back. Then i get a call back from Melicent(service department) to say that Chantelle is off sick till the 3rd of March. So how is she on a call and at the company on the phone at the same time, and why was nothing mentioned to me she is actually sick. Obviously the curve ball is with the dealer as they were not aware i bought the car 7000km back from them and clearly they *****ed up somewhere with the inspection. There is 2things i hate in life, someone lying to me and someone trying to ***** my money, and in this case i get the feeling they are doing both
