ADT - worst customer service

No customer service or response. I took out a policy with them end December where they indicated that it's 3 months free and my first debit order would only go off in April 2023. They already deducted two months premium and when I send a email why I don't get any response and called a few times put me through to my credit controller and no answer. I also send numerous emails with not even a response. I also had to pay an admin fee which I did and then they deducted it from my account again as well. Also followed up with my credit controller, and no response AGAIN. Called ADT after I don't get feedback from the credit controller and ask to speak to a manager, was informed that she will call me, still no call from them. This is unacceptable
