Bad service with Netstar

I have had a contract with netstar car tracker for just over 2.5 year. faithfully paying my monthly instalments. After this whole time I had an incident that I my house was broken into and the ******* went away with my car keys but luckily they did not drive the car. Since it was around 2:00am when the incident occured I called netstar alerting them that someone broke into my house and stole my keys so could they at least notify me in case someone starts my car. They said they could not help since the ****** keys had a netstar modulator. They could only help if someone started the car with keys without their gadget.

I grudgingly accepted their reason and had to stay awake till morning. I then managed to get a new set of keys and surprisingly when I started my car I never got a phone call notifying me that unauthorised key had been used. To me that was a breach of contract because I was paying a premium for having those adons. I stopped the debit order and surprisingly that's when they called and threatening me with blacklisting because of breach of contract. But I told them that their device was not working at all but they turned a deaf ear.

Now I have to pay cancelation fees and all other stuff. They are just after your monies and I would never refer anyone to them. I feel cheated
