IN-HOME EXPERTS

Why are in home experts allowed to come to your home without customers consent?  Why do in home experts enter your home under false pretense? There's no soliciting in our neighborhood so sending out a in home expert who states they are here to supervise/manage an installation THEN try to sale you a cell phone service package is fraudulent.  We signed up for internet service not to be solicited for other services while trying to enjoy our Thanksgiving holiday weekend.  This is unacceptable and needs immediate attention!!
