First Help Crashed into me speeding to an accident!

These tow truck drivers are chasing money and in the process will disregard any types of road laws. Case in point, I witnessed an accident yesterday in Lavender road, Pretoria. Seconds later this First Help towtruck, driven my Gerhard drove into my vehicle, trying to get to the accident. Literally causing 2 accidents at the very same location. Now to try and get them to fix/repair my vehicle is a daunting task as Gerhard's supervisor (David) is very ****y and David's supposed supervisor Wimpie does not answer me, even though he is the one apparently dealing with these insurance matters. They are all from the Watloo offices and trying to contact the office is also not working as none of the numbers are working. I want answers as to when my vehicle will be repaired due to your drivers not knowing how to obey road rules. I accident report was logged with the Sinoville police station and this information was supp**** to Wimpie... again with no feedback from him or anyone else. Furthermore, if I do not receive a feedback by COB today (7 Dec) my next steps will be legal recourse.
