The best solution is to get a call-blocker. I have one, and my phone is silent. See my post on whocallsme for 305 918-2338 for more information.

Yes they are really pain in the butts, but very annoying, don't know what they want..They keep saying another woman's name, keep telling them she doesn't live here. They call every 5 -10 min apart.

Calls at least 15 times per day.  Starts at 9 am until 9pm
