Welded lower control arm not in the report and no care attitude at George branch

I was ashured that if something popped up not on the Dekra report, I would get it sorted out. So, there was rust, for the price it was ok. I started fixibg tge car and then.. I found a welded lower control arm fron accident damage. A welded controll arm with cracked welding withe s****yard marking still on it.A piece welded in just above the ball joint. Their vedict. Its in the report and it is not dangerious. Doing their best to cover themselves at the George branch. I have photos and the so called report. . There is no menrion of a welded controll arm. Its all good if you are lucky and there are no faukts. But this is ridiculous. The welding looks lije it was done by a child. How did they miss that and why are they not owning up? For a R1200 controll arm , I must now endanger mysekf and other road users. This car was bought while my other vehicke is being fixed to be resoled. I cant do this to soneone else... the manager has not even bothered to phone me. I AM JUST A NUMBER. The wheel turns, what you reap, you will siw.
