I was hounded relentlessly by phone last census (I thought we were unlisted but I suppose they have their ways) so much I had to screen the calls with the answering machine. I finally picked up the phone and requested to be placed on their "do not call" list, heheh. LOL, you can probably guess where that led.... said she was from the government, said they didn't count. Eventually she got around to threatening me with a fine. Idiot stopped calling after that. Thankfully I am nowhere near census creeps this time around.
We don’t have a land line so they’d have to call my cell phone. The may have the number, may not, but I monitor the phone numbers when called.
If they call, I’ll tell them the same thing I’d tell them at the door, then hang up.
