Horrible service - want to cancel my car insurance

<p>I called discovery to add my tracker on my car. They delayed to get the tracker installed only to realise later that its not working. When sending an sms to see where the location of the car is, I get no reply. Have wasted my money for 3 days t calling discovery to fix the problem. I get no help from the DQ tracker. Im really angry as im on matenity leave its costly for me to keep calling them for the same issue. The service I received is shocking. Spoke to Gabriel the manager still got no help. What can one do now??</p>
