cancellation that is not attended

Policy no: 22PHI401. I cancelled my ADT alarm services in April 2022 as I was moving to another provider. they are still deducting from my bank account, and I am now paying for 2 alarm service provider for 2 years. I sent an email to them on 29 Nov 2022 and no one responded but they are still deducting from my bank account which is causing a lot of financial inconvenience on my side. I want you to assist me to resolve this matter
