I had a similar situation a couple years back-them calling from about 3 or 4 numbers daily. I rounded the numbers up and found someone in the local office who cared enough to help me and the next day the calls stopped.
This is the FIFTH call from the American Lung Assoc. I told the lady I had already told you to stop calling me I am NOT interested so STOP calling. She hung up. Only problem you can't block the # because each time they call, a different #. BUT this is the second call from this particular # Here are the # they use. I am trying to document day, time and #
My first call from 202-770-2406 today. This after many calls from the "IRS" at another 202 number. WoW these people are relentless. They are bound and determined to take our money from us. The funniest thing happened, my husbands cousin got an "IRS" call threatening his wife. His wife has been deceased for at least 12 years. He went nuts on them and they hung up on him!! LOL
