I came up with a new line that has been very effective in getting unsolicited sales callers to hang up real quick and hopefully wipe my phone number from their list.
fortunately there is caller id and if it is a number or person I dont know I answer the phone. but being a bit of a joker that I am and usually just answering the phone when it rings its very annoying getting lots of harassing calls for donations and discounted home repairs and whatnot. here is the line I came up with that has been working great.
"computer repair solutions, please enter your ten digit code number and I'll connect you to get all your computer problems resolved."
this has been very effective so far.
you can always replace the word "computer" to something else like "credit" or "real estate" or whatever. you want.
if they ask questions I just say "this is a connection service, enter your ten digit code now"
if someone ever starts punching in digits, I'll just tell them that it is the wrong ten digit code. but it hasn't come to this yet they all have just hung up.
