Matrix/Beame - Misinformation

My old contract with them expired and I never cancelled, but downgraded to a monthly subscription. Now that I have sold the car, I have been told that I have to pay a huge settlement fee! It was not stated anywhere on the contract information that was sent to me that its a 36 month contract and no direct link is available to the T's and C's in the email to explain this. This is unacceptable and I do not recall the consultant who sold it to me telling me this at all! I would never have agreed to this if it was the case. I will NEVER buy this or any brand-related trackers again.
