calls coming into cell phone several times daily.  no information found to identify company. no message left.

I'm also receiving these constantly, at least one time per day. Every time I answer it's silent on the other end. Cannot call back due to it being an invalid number.

Update on this, I just answered the number and finally got somebody on the line. This is a company "claiming" to be responding to a request I made regarding consolidating my unsecured debt. I have absolutely no debt nor have I requested assistance, so this is most likely a fraudulent scam.

I keep receiving calls, no answer on the other line.  It's driving me nuts!  My number is registered with the do not call list, I am going to try to report them that way.

Have received several of these calls several times a day (over 20) on my cell phone and my home phone each.  If this is a collection agency, I am not sure how they are accomplishing their goal by not telling me who they are, what they are collecting, etc.I finally blocked them.
