Unsatisfied complaint outcome with no supporting evidence

On requesting my DQ-track movement report I notice that there was no movement recorded from the 10th of September 2021 up until the 2nd of February 2022. Upon enquiry about this, I was very disappointed to hear that my Ctrack device was not working nor tracking for more than 4 months. I, therefore, was paying for a service that was not working, without any notification from discovery and was confused as to why it was not picked up. What does it mean to have a Ctrack device if it's not picked up that the device is faulty and not tracking or that no communication of battery is disconnected or ******? This after Ctrack came out the 19/07/2021 and said nothing was wrong with the device. 3 months later clearly the device was faulty. I requested a refund for the time paid towards this service on the 27th of July 2022 . Discovery Insure management team responded after numerous follow-ups by my broker on the17/08/2022 to my complaint, that the last repair was done on 19/07/2021 and they made a decision not to refund as the tracking unit was in a working condition when it was removed on the 5th of August 2022. If it was working why was there no movement record between the above mention dates? On requesting evidence to support their decision, especially focusing on the above mention dates where no movement was recorded, myself nor my broker received a reply to date. If this is how a complaint gets addressed and I have been a loyal Discovery Insure client since 01/06/2016. I'm definitely considering moving my business to another insurance company
