I dont have a canvasser, infact I dont canvass .
But could the problem be the homeowner divulging information to a third party (as they see it) .
If I were not a window cleaner and a canvasser knocked my door of an evening on behalf of a wc I'd never met and who had not yet actually materialised to clean my windows I would probably feel the same.
any new customer gets my full name , address and telephone number at the door on completion or during the work, and I ask the same of them.
They have the option to pay in future by bacs, I have their surname for that reason to identify payment on my statement and I take a telephone number (landline or mobile or both ) so I can chase any non or late payments without having to leave my sofa, sorted
