Very bad service

The service is disgusting when me and my partner first took the package it was working well till the time there was looting our car battery was ****** but we never received any call regarding the car, that's when we noticed that we no longer getting service from Cartrack until we reversed payments and complained on Facepage, then we received a call and someone apologized and promised to fix the problem and we agreed that the money can be debited since it's still in the back account. So since the looting we had borrowed a battery from someone else and today 11 August 2021 we managed to get our own battery and removed the other battery still there was no call so clearly the initial problem was not resolved. How do we go ahead and pay for services that we are not getting? We would like to cancel and will not pay your penalty fees and I would gladly like you to come a collect whatever device you put in our car as it is not serving any purpose, like how do we stay on a call from 15:59pm for 47m 6sec and still not get answers we were transfered from control to accounts to fleet and back to control where the supervisor by the name of Nthabiseng couldn't talk to us and hangup. We just want to cancel.
