Bad Service/Cancellation of policy

I really do not know where to start because Cartrack is just not taking care of their clients ,iv been with them for more than a year even worked for them but trust me the service is very very bad ,I have an existing car with them under business,Noticed later which I was told I need to check my unit in 3months ,the previous tracker I used was tracker connect and never experienced any bad service viva to them cos i never as a customer had to text or check my own unit that I asked ask them to do ,Yet I had to pay for something that will take care of my car little did I know car track is giving out **** service cos I had to call and report the unit now they telling me I have to an extra amount to commit on something or rather for theory had it installed,I’m so mad I even want to close my account, when I called I was scheduled for the unit to be checked that was on Thursday 25 Jan 2024,the car is not switching on not even the cluster is showing anything I called the guy back who is Sipho Car track the Technician to assist because after they checked the car it’s not driving,I would like to cancel my contract and maybe go back to a network service provider that will keep me posted when the unit is not responding or what commitment do I need have and say if I will be able to do it or not #Cartraack is Trash and they do not value their customer,trust me I just had a small issue but now it’s resorted to bad and awful service I dnt trust them anymore,they do not keep their word for it.Im also reversing the debit order as soon at its Monday morning!!!!!!!im done with Cartrack it looks like they only after ur money and not the good service,I’m Donee
