Called cell phone--no message--tried calling number always busy

I did not answer, because they keep calling day after day. Maybe two times or more a week. I try to avoid them by not answering when it rings.

I do not know anything about them. They are calling me and they do not leave a message.

Calls daily to my work number. Message to hold for operator. I hang up or it disconnects.

They ask for one person saying they are in the area or that it is about a letter they sent , now today it was from Lydia Martins Office about a business opp. We have ask several to be taken off the call list, today I was told try and make us.

Person just calls and is talking in the background but doesn't say anything into the phone. Call back and the computerized operator puts me on hold

They call 3-6 times a day. I now have them in my phone book with a silent ring, but the missed call alert goes off.... and my incoming call list is unable to be navigated it is so clogged with them. But at least it wont ring. I havent answered their calls in the last 3 months, so that is the last 200 or so phone calls, they still call me. Asking them to stop obviously does nothing. WHAT CAN WE DO???? I dont want to change my phone number.

Shows up on my caller ID. I do not answer unknown callers.

I have told these ppl I don't want a loan and they keep calling and calling and calling. Now they don't even ask for me, they call and when I answer they just hang up. My number is private, how are they accessing it?
