Contract Cancellation

2024 October I called Tracker connect wanting to cancel my policy, but I was told I will be charged a cancelation fee,cause my contract only ends in February 2025.i decided to keep the policy and wait for it to end in February. To my surprise I'm told I owe them for March and April, Tracker decided to put me on a month to month contract that I was not made aware of and I did not agree to. When they call me I was threatened that the account will be handed over. If they could decided on their own without my knowledge that they putting the account on a month to month then how do I owe them. They did not call to even ask if I still want to cancel. The way they have capacity to call and convince you to install the device I don't understand how the failed to call and notify me of the changes.I am not happy that they even threatened to hand over the month to month outstanding amount that I did not sign for.
