Bad customer care service

I have been a client with Ctrack for years now. I have three vehicles with them, all for business purposes. With all my vehicles I get ignition on and off sms notifications. About two weeks ago I realized that on my one vehicle I only get ignition on sms and not ignition off. I have been phoning Ctrack every day to get this resolved as I need to know the where about of them at all the times. Each time I get told the system will be reset, sending polls from their side and mine, then I was told the problem is on my side! But I'm getting all my other notifications except for the ignition off on one vehicle. Yesterday when I phoned a supervisor was suppose to phone me back to finally get this resolved, which obviously never happened. The number I have been using is ***. I have dealt quite a bit with Christiaan there, that's unfortunately the only name I have. My customer no is ********** 2. The vehicle in question's registration number is YRN368GP. Do I have to keep on phoning every day to get this resolved just to be told the same thing each time!!!!!!! I'm really appalled by the no care attitude and its such a well know company who cant even rectify such a minor problem. What's going to happen if I have a serious problem?????
