Unhappy with service

I have a car insurance with discovery since 2017 and DQ tracker which belongs to discovery.

I called in for roadside assistance on the 8 July 2021 at 16:25 I was on the phone for 7minutes with a call centre agent, he advised he can not track my car to get accurate coordinates of my location,i was stuck on the side of the road. For 7minutes discovery could not track my vehicle.

This mean i could be hijacked and my vehicle would not be trackable while i am paying for tracker with discover.

Secondly i called discovery to review my premium and they refused instead they advised they can change my plan to a cheaper plan but not reduce the amount that i have been paying since 2017 until 2021.
