I installed their track 2020 around March and I have been experiencing problem with their tracking device, panic batton never worked and I have been reporting the fault to them. They have once sent a technician to come to attend to my peoblem but instead of my problem being resolved their device now affects my beam light bulbs, every week I must replace them, I tried number of times to register my complain with them, all they do is to call me left and right collecting money, which I protest to pay untill my query is resolved
