they called me 4-5 times over a 1 hour period every day for 2 weeks...i told them wrong number (it was for someone else, not me) and they kept calling. I told them to stop and i'd call the police if they didn't stop harassing me. THAT WORKED!
We received 10 cals in about 4 hours time, I called them back and no one ever answers. Cell phone compnay cannot do anything about this, advised me to enter my number on the do not call list which I already had done over a year ago.
