Unsatisfactory Worksmanship

In January 2015 our car (primarily driven by my wife)was involved in an accident, hit at back by a truck and the insurance assigned TC Panelbeaters in Wynberg as the repairer. The car was drivable with no issues except that it was dented.On the 30 Jan 2015 it went in for repairs and came back on the 17th of february 2015.They did an excellent job when it comes to the body repair, in the process a lot of electronics were affected. Currently the car is parked to minimize the risk of further damage. Their technician failed to solve the problems.<br> 1. ABS lights are ON.<br> 2. Slippery Terrain Light ON while driving on a dry surface.<br> 3. High temperature light ON. Car was boiling after less than 8KM of driving.<br> 4. Sunroof no longer closing automatically as it was before, now it requires a key to be turned ON before it can close.<br> 5. The aircon is blowing air in reverse, very cold air comes out on the front bumper grill.<br> From the 18th Feb2015 I have been trying to get this sorted but I was told to try and bring it in again for checkup. Now I'm expected to cover the cost of towing the car back to them for checkup. I was pleased by the work done but disgraced afterwards. Thanx
