Alert unit not operable - Technical request logged

I logged a technical request to have my Alert unit fixed as it is not operable. I have not heard back from tracker, I did however get a sales call from them and was assured the technical department will make contact - nothing to date. So if my car is ****** I guess this is the type of service I can expect.<br> <br> I am also paying almost R40 more per month than the advertised price on their website.
