Terrible service

I started experiencing problems with this company shortly after they installed a car tracker in my car. A few months into the contract my battery died in my car and I never received a notification or got a call from the company like they had promised to do. When I queried this with them I was told that my tracker was disabled and that they would send someone in to fix it. I don't know how it had been disabled or how long it had been like that. This happened twice. The third time around my car was broken into and my battery was ****** from my car. Again they did not pick this up, saying that the tracker had been disabled - again! They sent someone to "fix" it but at this time it was too late since I had already had to replace the battery in my car. Basically this service never worked whenever I needed it to. In addition, the "happy button" which is a service that provides me with fuel when I run out and I am stuck never worked either. I was instead told that I could not be assisted even though I was paying for this service. This meant that from October 2016 I was paying for a service that I never got. In October 2017 I finally decided that I was cancelling the contract because I was not satisfied with their service. I contacted them and they sent me a form to fill out. I did this accordingly and expected that the contract would be cancelled yet they are still debiting my account every month. The last debit they made was yesterday 10 January 2018.
