Greedy people and agents

Cartrack wants to reep me off and is harassing me now the called Terrence. I wanted to cancel the contract prematurely,they told me I will pay cancellation fee and I must wait for November 2021 so that I could not pay cancellation fee.then I waited for November but they still wanted cancellation fee I said they can take it Which they did. Now this Terrence is calling me again and he does not want to listen to my reasoning he just want to collect money when I start to explain he dropped the phone on me. I will never recommend anyone I know to take cartrack.
