Called and didn't leave a voicemail.

Called me & hung up

When I call back I get a busy tone.

constantly calls, no messages left! when i answer they hang up. Don't know who it is.

This number has called me several times leaving me threatening messages. (Stating that there is a federal case against me saying that i have missed the last two payments of a payday loan. I have had payday loans out and they are all paid in full. I am also getting these calls at work too.Please advise me on what to do.

This is a scam number, received by information by pfishing pay day loan companies. Do not answer the phone, they are just trying to get money from you that you do not owe!!!!

I see the number pop up on ID and don't try to call back to find out waht it is about and the line is busy, everytime I try back.
