Disappointed in ADT customer service.

I called ADT because I wanted to know why my account was debited twice. The call was answered by Lilly who transferred me to accounts department. the call was then answered by a RUDE person called Mary. Mary was not listening to what I was saying , she was just interested in saying what she wanted to say. I CALLED as a client , I had a query, why not listen first before you answer? I had to drop the call because this person was not even aware that I was getting irate, she went on talking. My query is still not resolved. I need a professional person from ADT to call me to LISTEN to me and help resolve my query. Not someone who talks over clients without listening first. I am very disappointed in ADT customer service.
