ADT unwanted e-mails and I have never been a customer

Have communicated directly to ADT and via HelloPeter about the annoying communication they continue to send me. Unsubscribing on the useless e-mails received doesn't work either. I am not a customer and never have been and never will be and dont appreciate been referred to as "Dear Customer". What they apparently fail to grasp is that it is not good PR to irritate people.
