Called my cell phone but left no message, but when I called, no answer... how did they get my number?

(310) 485-8904 DEBT MANAGEMENT called at odd times repeatedly, like 7 AM Pacific time, then 11:14 AM, no message left. There is no answer when calling back and no answering machine, it just rings forever. We are on national "Do Not Call" list.

I have been recieving calls from Debt Management for over a month now! I am not in any debt and do not know how this company got my number! They have called from 310-485-8904, 310-485-8982, 402-982-0464, 626-273-8263, 562-289-8199. They call early in the morning and several times in the evening.  Each time I answer the phone they just hang up. When I call back the phone just hangs up. I have tried to find out who these people are but have had no success! A friend of mine says she too recieves the same calls several times a day.

I have gotten several of these calls, but each time I pick up, it disconnects....any idea who they are?

I am getting these calls at all hours of the day and night. It rings once and then hangs up. Annoying!
