Cartrack - worst service

I wish I had not taken this Tracker from this company. I called their centre on numerous occasion just to verify if they are tracking my car. I was told my car was not being picked up and after months trying to reach out so they can arrange for someone to come and repair/check what's wrong, I am always told a ln email has been sent and I should await for feedback. This is frustrating because I am paying for this service of which isn't offered. I feel ****** all this time and want them to answer and pay back my money for all this time I wasn't being covered.
