ADT Security Accounts and Contracts

I cancelled my services with ADT in Oct 2022. Up to today no one from ADT has contacted me as requested numerous times where I was promised that someone will contact me if I call them. I have no information regarding my request to cancel my account with ADT due to affordability, nor any communication or reply on my request to cancel. ADT then proceed to deduct funds from my account without authorisation. According to the latest ADT account this was only due on 31 December 2022. I still do not know if my account is cancelled. The service you get from ADT's contact centre, customer support and accounts are condescending and appalling.
