Car track

Car track is taking money out of my account yet payment is been made, The tracker unit is draining my car battery,im on my 2nd battery and they don't wana cancel my contract and is asking for a payment of R2300, yet I wana cancel because they at fault, they refused to buy me a new battery, and there own technician came and showed me and told me theretracker unit was damaged and that caused my car battery to get damaged, they are a *****ulent company,how can they take money on there own free will,that's *****! Please don't make a mistake putting a tracker with the car track company,When you call Juan Steynce he manipulates things and trust things around which is ***** and is not responsible for there wrongs..
