Paying and on time every month for the tracking device that is not working,

On 31st May2024 I noticed the tracking device has not been working since 9th April 2024, I called the call centre, which confirmed the device is faulty and it has been flagged, and someone will call me soon. 3 hours later no call, I called again to be sent from pillar to post. Monday 3rd I called again, same to be told to hold and hold. I sent the e-mail still awaiting response to date. From the 9th April they could not even pick-up that their device is faulty, I had to find it out myself, and an attempt to alert them was just a waste of my time and money. Until today 4th June I am still waiting for that precious call, and their debit order goes perfectly on time every month for service never rendered.
