Unfunctional system pathetic service

Had Netstar tracker installed 7 years ago. I was told I could test the system twice a year only if I wanted to, they said at the time it was not complusary to do so. I checked it the first year and it worked so I didnt check it again thinking that netstar would pick up when it wasnt working. I decided on Saturday 3rd March 2018 to test the system while we travelled on the N2 however after about 30mins of trying to locate us the consultant called to say he cant locate us and I must call the call centre on Monday to report it, he couldnt do anything else to help. So on Monday 5 March 2018 i called the call centre only to be told the system is probably old and needed to be upgraded!!!! . This made me really upset as now I dont even know when it stopped working yet I was dilligently paying my monthly bill. No one ever contacted me to say I needed an upgraded system yet they have all my contact details. When I questioned the consultant he said he cant do anything he will get a sales person to contact me urgently, it is now 5 days later with no call and no tracker so what happens if my car gets ****** in the mean time. I feel this is truly pathetic service. I would not recommend this system to anyone. I think its time to get a new service provider.
