I had that noisome twaddle happen after the property transfer...Do not call is fine but it's by no means immediate.
I just went onto the Erotic Services section of Craigslist and got some whore's phone #'s I gave 'em.
However if and when they called me back I have caller I.D.so I went into "pimp mode".....It's fun to f*ck with these telemarketers heads,some of'em just don't get it,which only increases the fun
