Netstar negligent on my vehicle caused severe damage to vehicle

They dont even deserve a star. My experience has only been bad with them. When I bought the car ot took them 2 weeks to contact me to install the unit, the guy was here for over 3 hours installing, not long after that I noticed that my vehicles computer box is acting up (in a bad way) then the unit started sending out false signals non stop and my computer box got worse. I reported it and insisted on it to be replaced, omw what a story having to wait for them to call you when you log a complaint on fb or call. Eventually the unit was replaced, that same day the gentleman that installed the second unit informed me that the guy that installed the first unit skimmed into the wires of the vehicle and they are not allowed to do that he will report it to HO, he obviously never did cause I never heard from them despite me complaining on fb why did he cut into my vehicles wires no wonder it is giving problems on the computer box and when I start the car I shock myself (this vehicle was not like that before as I am a very difficult person and had that vehicle checked with a fine eye before purchase). Not long after second unit was installed the same issues of false signals started again but this time 10x worse. I reported it again an was just ignored, their fb people are unbelievably spiteful, so after 2 weeks of having to repeat myself over and over again on the second unit and the wires, still no help. The problems on the vehicle is getting worse but Netstar just dont care. Then they call me and tell me out of the blue that the supervisor himself will come look at the SO CALLED WIRES so I phoned my attorney and he informed me that the supervisor can have a look but he needs to bring both technicians with that installed both units so that they dont say back at the office oops let pretend we didnt do it, they must admit the quilt infront of me and the supervisor, I told them the way I was informed now they are totally ignoring me after I requested for it to be done with all 3 parties from Netstar to be present and now that I reported it to Dial Direct as Dial Direct uses netstar. They are ignoring me plat, put phones down in my ear, they fb people read my messages and dont even have the decency to answer me back, no one calls back they just ignoring me flat now. I have decided to make use of my attorney to open a case with the Ombudsman (MIOSA). I want real mechanics to look at the wiring that was damaged by netstar and write me a report in order for me to send it to as many newspapers as possible, I know the Rekord in Gauteng are very willing to do an article, I have a few people on fb that the same was done to that said they will testify that the same happened to them with all the proof need. I am looking for other places where this can also be reported for more people to see and for people to help me to get the unit out and explain to me why they skimmed into the wires and who is going to fix that.
