This ADT ****** my money in my account.

I bought a house few month ago. When I went free they was ADT alarm. Then the told first owner as contract still on which means they will transfer it also to me. I send Jenny email that told her am not continue with a contract. the lady I was speak to her. She told me She will speak with the lady of acc department. They will refund me. I was waiting until Jenny told me I ve reverse my money. I did that and I do stop payment. But now this morning I realize this ADT security they went through again to my account. So my question is how they debit my money without my permission. Worse part I do stop payment as well that shows them clear I don't need them. As if now am owing them. People be to be careful with all this fly by nights companies like this ADT. I need my money back. And now I also going to see Wendy Norllar. As I spoke with her before. And I told her wat Jenny said to me. Worse also the old owner of the house email them. Told them they mustn't continue with me on that contract. But ADT did by force. They r the thrift. Also hello peter do your best
