Zero Stars not 1

I changed my insurance company last week and when they asked for a copy of my Matrix Tracking Installation Certificate, they said they couldn't accept it, as it showed the incorrect model of my car. I had not noticed this, as I watched the installation engineer take down the correct model of my car, therefore I would not expect a basic error like that on the insall certificate. I called their 'so called' Customer Care line, 10 times last week and the line just cuts off. I tried again yesterday and eventually reached someone. I have just spent 20 minutes on the phone with him, expalined their error and he could not could not find my car model from his list! He also said he could not add it manually, as it had to come from their database list. He checked 3 times, but still could not find the X5 M50i model, which is a very standard and popular model in SA. I had no choice but to tell him I would need to cancel my subscription, and I subsequently sent a cancellation email to the email address he gave me. I explained their error and that I have been left uninsured and can a manager call me urgently to discuss. I still have had no response. MORE IMPORTANTLY, my insurance company told me that because of their clerical mistake, I have essentially been driving around uninsured for the last 7 months, as my cover relies on having an active tracking system. Therefore, with Matrix Tracking put my car model down incorrectly, had I been involved in an accident, they would not have paid out, because Matrix Tracking put the wrong car model on the certificate. Given that the Matrix Tracking service advisor could not find my standard car model on the database, it would seem that, instead of your company investigating the error and fixing it, they decided to insert some random model intsead and leave me uninsured. My attorney feels confident that there is a strong case for negligence and breach of contract and I feel that this is worth pursuing.
