Deceptive contractual obligations from netstar and poor service delivery

In 2017 I was coerced by Auto & General to install a Netstar tracking system to my vehicle because my premium would be less if I did so. They did not mention the 5 year contract over the phone. It was only after the device had been installed that I was called and made aware of all the more binding details of their separate contract. After installation, half of the electrics on my dashboard stopped working including my radio. I called Netstar, they sent out a technician. He said they were unrelated. I later saw an auto electrician who assured me they were but because I can't say prove it (installation being top secret) I had no recourse to take the issue any further. Now 5 years later, after not one email or call to update me on my policy or device, I call Nestar to cancel my subscription. I am told they cannot help me, they will call back within the hour with someone who can help me. No call happens. I call back. They inform me they need 30 days notice. None of which is mentioned in the booklet with the certificate of installation that I was provided with. None of the website addresses work in that booklet either. I eventually find a new secure website for netstar. In the terms and conditions nothing is mentioned of the 30 day cancelation notice. Only hidden deep within the clause for duration of the contract is the 30 days notice mentioned. I was told they will then send me a confirmation letter to confirm cancellation of the contract, which I still have not received. These deceptive contractual obligations are so outdated and are considered suspicious and very poor business practices. I'm fairly sure this would be considered to be against the consumer protection act where such loopholes are to be made transparent and clear to all consumers. I certainly never had these problems with cartrack whom I used for 5 years prior to trying Netstar.
