****med into a 36 month tracker contract. Misleading insurance

Pineapple call me and informed that they need to install a tracking device on my car which they will be liable for ( I had my own tracking device already which I shared the information with pineapple). They advised that the second device is at their cost as part of the insurance cover. I cancelled the insurance with pineapple and now I am told to pay cancellation fee for the tracking Device also because it's a 36 months contract( I was not informed of such otherwise I wouldn't have agreed). pineapple was so misleading, people must be careful
