Netstar is an abusive useless company with no ethical values

My name is Siyabonga and I'm very frustrated by Netstar.I have about four case numbers from them complaining about how they have been treating me and they haven't responded to even one of those cases.I asked them to Uninstall and re-install their gadget from my old car to my new car sometime in April.They charged me 650 for that and the premium would be included in there.It took them about 15 days to re instal the unit after Uninstaller it and keeping it with them,after that they charged me a full premium and for a unit that was not in my car for 15 days,they overcharged me on the de install installation as well and I've been calling them ever since,I've been complaining to them for over three months now all they do is say we r escalating the matter and I never hear from them.even if I were to call today again they would give me a fifth case number and never attend to it,they recently debited 845 from my acc and I called them and they said they made a mistake and gave me another case number and never got back to me as usual,I'm just waiting for my contract to end and leave this demonic company,they don't care about their clients I'm so angry at this useless company
