Billed for inactive service

Query:<br> I took a subscription of a tracking device with Tracker Company in September 2014, I was hijacked and the car tracking signal had never assisted or retrieve the location of the car, when I called tracker the confirmed and they emailed tracking report for insurance purposes that they cant locate the car. I then called to ask what will happen to my subscription and was told it will automatically cancel that was December and the hijack took place in November 2014. <br> <br> The insurance processed and finalised my claim in mid December and in January I was called by the police to say my car was recovered by SAPS who were in patrol as normal (Not tracker investigators) at the place called Soshanguve, in that very same month later I saw debit on my account and I called to ask why am I billed because the tracker not working and the car was recovered by SAPS not with any assistance of the tracking device. <br> <br> Should i be subjected to pay for this? what service am i paying for?<br>
