Worse Company Ever with the worse Customer Care

Where do I start. This has been by far the worst service provider I have had. Firstly, I called the customer service centre to speak to someone and the lady was so rude & irritated with me, she first gave me the wrong registration and information and when I told her to repeat herself she sighed and said well this is the information she has on the system for this vehicle (wrong make & model) When I corrected her, she was even more irritated with me & continued to talk over me, is this how customer care is? Now for the actual problem, In 2022 the unit stopped picking up signal in November & I opened the app in December. I logged a call & it took the company about 2 weeks to come & repair the unit. Why was I not notified? The loop hole is that I am accountable to test the unit every 3 months? What do we pay for because to take the money or to make the sale it is extremely quick but to be notified that a unit is not working then who cares right? In January the unit started draining my battery, my car had just gone for a service & the car is barely 1 year old but the car was stone dead. I get notified about the vehicle losing power while the AA guy is trying to boost my vehicle, please make it make sense for me. Why when the car is being worked on then am I told the car lost power & not when it actually lost power? Again now in February the car is dead, same story with being notified about the power loss on the vehicle. Now if I wish to cancel I have to pay the remainder of the contract but where am I notified on time for the issues on the vehicle? Where am I refunded the premium if the unit is not working but no one tells me? This is so frustrating because should the vehicle be towed while it is dead, how would I know? Who is going to be accountable for this? Honestly worse experience ever!
