stop giving your phone # to strangers at your front door. this is how the "leads" are generated. at some point each one of these people complaining were aproached by a stranger in a PWS polo who talked to them and attempted to set an appointment, and gathered info in order to visit the appointment. Whether the homeowner did or did not have a sales demo done at their home, the phone # is used to continue to attempt to sell product. Amazing that people in this day and age freely give out personal information to strangers and are displeased that people use this info to solicit them.  Oh yeah.....the sheet that those guys in polo shirts are writing the info down on, has the legal small print that allows them to use your info for further sales attempts. use your head people, if your not interestedin buying,tell them NOTHING
