faulty tracking device - poor customer service

found out after tracker was installed upon taking out insurance with ffw that tracker is not working phoned ffw from mon 01/07/2019 EVERYDAY TWICE they promise someone will call back but no one does yesterday the call centre agent said that their manager will call me ......still waiting .....paying since 2012 for non existing tracking device. altech netstar is just so bad no feedback from them either what gonna happen should my vehicle be ****** nw.... FFW just gonna say my device was not working properly? and every month they take their premium religiously- and if i refuse to pay the premuim they just say: Ma'm ur not covered for that month. but i've been paying since 2012 and have been covered PARTLY anyways...... sad
