Damaged engine due to faulty repairs by Insurance

in January 2014 I had a small accident that damaged the front of my Kombi as well as the radiator.<br> Although i told the assessor that my mechanic said the whole radiator needed to be replaced they only \fixed\" it. It continued to leak slightly but unbeknown to me started to overheat and was not noticed until the mechanic heard my water boiling although it showed that it was cool. Now the consistent boiling water has damaged the waterpump, the thermostat as well as the HEAD. And now I cant drive. Now Dent Doctor refuses to acknowledge that they were at fault and tells me since they did not work on the Engine its not their problem!!!! <br> I am tired of fighting with Hollard so I will change my Insurance company but also go to Clientele Legal to sort this out. The damage to my car is now R8000 as the head must now be repaired as well as all the water housing that has been damaged due to the boiling water.<br> "
