No Business Sense

I have x2 Cars active with them and X1 Car I have sold. I asked them to remove the tracker from the Suzuki which I was selling and add it to the New Car I had purchased,which they said they do not do. I was left with the choice of paying for the cancellation fee which I said to them,If that is the case,The contract is left with 1year,it is Okay,continue with Your premiums until the end of the Contract-which they refused. Now they have deactivated the x2 other Cars and collected the Premiums...
