I keep getting calls from this number and when I call back it rings once and then a busy signal.

They call several times a week. I never pick up and they never leave a message. They use different numbers - under a different number it sounds like they do direct marketing for various organization.

This number was on my caller ID 16 times in the last 2 weeks - they never leave a message.

Cannot get this number to stop calling. reversed called it and get a recording saying they only call business numbers and to press the number 1 to remove from list but nothing happens when the #1 is pressed

prank call, it rings and hang up when you pick it up. every hour for past 2 days.

"U have won soo much money here, press one now"

I received a phone call from them on my cell phone and I ignored it twice. A few seconds later, I received a voicemail, but they didn't say anything.

he said he was from a collection agency....

Caller calls several times a week several months now. Never leaves a message. Refuses to identify himself. Hung up on me today and when I call back refuses to answer. Do I call the police next?

various.

This man with a foreign accent keeps calling me saying that I owe money and that I or my attorney must call him back.

They call and can't understand what they are saying.

unknown-saw it in my call numbers on cell
