Highly Disappointed and Dissatisfied with Netstar

I have being with Netstar since 2012 or 2013. I used to perform routine check up on the device every 6 Months until I stopped during lockdown . Last week i was surprised when I tried to perform a routine check up on my tracker device and to my surprise I was told by one of the consultants (Njabulo) that my device needs an upgrade. I asked when was I going to be notified if I didn’t call in…..I was further told that Netstar is unable to locate my car unless I report it ******. My question is what have I being paying for every month….I then cancelled the contract with immediate effect. I am highly disappointed and dissatisfied with Netstar For the service I’ve received after being with them for so long. At the moment I believe they do not deserve 30 days notice for cancellation of the contract bcos it looks like I’ve being paying them for free. I cant report a car ****** when it is not for them to be able to locate it.
