I have rcvd a call from this number a couple times and never answer but they also never leave a msg. I tried to call them back today and its says it is not a correct number... hmmm weird

Same thing is happening to me

Yes, I've been getting that for a few weeks now.  Same thing, call back and the number's out of service.  Only, for me, the ring happens in sections.  It's like they're calling four times in a row, as the ring happens for half a second, then comes back a couple seconds later.  Just called me again for the third time today.

This number has been calling for a few months now.  The past few weeks, its been several times a day - EVERYDAY!!  Most days, it is at least every 2-3 hours beginning at around 8 or 830a until around 8 or 830p.  Same as other posts, nobody is there when I answer and when I call the number back the number has an auto recording that it is "no longer in service".  

Sometimes my caller ID says: DENNEHOTSOAZ  or UNKNOWN  or  PRIVATE or  just the actually phone number appears.  

What can be done about this?  Something's got to give ... any suggestions???

I have been getting phone calls from this number, it started on Januaray 2, 2013.  First it was Wireless caller, and Unknown Caller. Now whoever this person is, they are starting to use peoples names, and Target RX.

They can keep calling, and I can keep ignoring.
