Still being billed for Beame contract that should be cancelled.

I was looking into trading in my car, so I looked on the website for email contacts and found the Customer Service and Tracking-Empire email addresses which I sent my query to. I was contacted by Shawn from Tracking-Empire sales and was told, via email, that the Beame tracker contract in my current car would be cancelled if I took out a new contract for the new car. I did this and traded in my car at the end of Jan 2020. I have since been billed and money debited from my account for both the old contract and the new contract in both Feb and March 2020. I have sent numerous email about is and the only reply I have received in a reference number. I want someone to contact me to resolve this and refund the two months debit orders.
