Yikes!!!! I have a little trick that I use with telemarketers and politicians that doesn't cause any damage to the property. Every time there is an election - local, state, national. I keep track of the politicians that use Robo callers. I then spend a little time looking up those politicians home phone numbers (if I can find a cell number even better). Then when those annoying telemarketers call I tell them I'm REALLY INTERESTED AND WANT TO BUY RIGHT NOW but I have my number forwarded to my work, so I'm on my employers phone. Could they call me right back on (insert politicians number) and it will forward to my cell phone. That way I get even with two birds at the same time, and the politicians number gets sold over and over as a hot number. I gives me great satisfaction in knowing I've help spread karma daily.
