CARTACK IS A ****!

I HAD A CONTRACT WITH CARTRACK ON ONE OF MY VEHICLES. UNFORTUNATELY, THE VEHICLE WAS INVOLVED IN AN ACCIDENT ON THE 30TH OF JULY. THE TRACKING UNIT FAILED TO CAPTURE DATA ON THE DAY OF THE ACCIDENT. THE CAR IS A WRITE OFF AND THE INSURANCE REJECTED THE CLAIM. I THEN ASKED CARTRACK TO CANCEL THE CONTRACT AND THEY DID NOT.THEY INSIST ON ME PAYING A CANCELLATION FEE OR THEY KEEP DEDUCTING MONTHLY PREMIUMS. I TOLD THEM I CANNOT PAY ANY CANCELLATION FEE AS THEY UNIT FAILED TO WORK AND THIS CONTRIBUTED TO THE INSURANCE REJECTING MY CLAIM. CARTRACK CALLS ME MOR THAN TEN TIMES DAILY AND EMAILS ME WANTING MONTHLY PAYMENTS.
