Car Track Unit Installed in 2023 and never worked - refused a refund

Unit was installed in June 2023. Device was giving alerts when it was parked in my driveway and the technician came back in July 2023 to repair. Everything was apparently working. I drive the vehicle and therefore I have never needed to track it. My husband drove it when we were in the Midlands recently and I happened to go onto the App to see where the car was and it couldnt find the car. The last recorded location was at my house in July 2023. Needless to say I asked for a refund as I had been paying my premium for 2 years for a service that I had never received, with no notification or alert from Car Track to say my car hadnt moved or that they couldnt track it. The customer service said I could add R30 to my monthly premium to get a lifetime warranty. They also wanted to charge me R600 to come and repair the unit (which was installed incorrectly in the first place) which I fought and they eventually waived that fee. So disappointed
