ADT SPAM Messages

I repeatedly get contacted by ADT via multiple channels (mostly SMS and EMail). Every single time I unsubscribe, but get contacted again a few months later.

I left ADT because of their bad service and continually increasing their costs. I respect my privacy and ADT certainly does not. I do not want to be contacted by them in any way or form. There is absolutely no reason for ADT to keep my details and feel that their spamming is infringing on our privacy rules.
