Still no assistance from Cartrack

I sold my vehicle and requested that Car Trac remove the tracker on 26/02/2021 so that it can be installed in my new vehicle as soon as possible. Car Trac confirmed that they will make an appointment to remove the tracker and re-install within two weeks. On the 04/03/2021 they debited my account with the March instalment as well as an installation fee (+-R 850). It is now the 24/03/2021 and the tracker has not been installed on my vehicle. I am trying to contact them for the last 2 weeks but no one answers calls. I have had no feedback from them and for the last month my vehicle has not been unmonitored as there is no tracker. Cartrack – please advise why the incompetence and terrible service? Furthermore, you guys make me pay for a service and have not provided it to me as yet. I have been a customer for nearly 10 years and I am very disappointed with the service. Could someone please respond to me ASAP. Contact : Yusuf Suleman ' Cell : ***
