Faulty tracking device

My name is Peggy. My experience with cartrack is so unpleasant. From March 2025 I have been experiencing problems with the tracking device they installed in motorbike. I called them and they told me there wasn't any fault with the device. For the past 24 days I've been sent from pillar to post and finally they admitted that their device was faulty and promised to send the technician as soon as possible and to date I haven't heard anything from them and I'm wondering what will happen if my motorbike gets ******, who will be liable, and they even told me I might be liable for paying something that wast my fault in the first place.
