security firm advertising through vandalism

A company that deems it appropriate to advertise their services by vandalising your property cannot be trusted. In what way is unsolicited advertising in the form of ******** stickers on your gates, intercoms and gate motors acceptable? who gave you permission? They clearly do not respect the people they want to do business with? and they claim integrity as a value? AND they are a security company? Also see the review under their full name too: K&N Gate Automation - not inspiring either
