The caller 'said' he was representing the firefighters of canada and phoning from Manitoba. He was looking for donations. He was persistant and I can not say he was rude. However, I do not deal with donations or business over the phone unless I initate the call... NO EXCEPTIONS.
Had a similar call, except he said the organization was "FireWatchers". I told him the number was unlisted, wasn't supposed to be in his database, and hung up as he started on about something or other.
Called yet again. I did not answer. These "Firefighters" request my husband (who has donated in the past : circus tickets, comedy shows, etc) and they hang up when they hear my voice.
I say give them a minute of your time and supply a FALSE credit card number. My favourite is to pretend I am a very young child ... then I have fun !
