I've been getting calls the last couple of days, with no message left, from this number.  It shows up as "ATT" on the caller ID, which made me think of AT&T, of course.  When I searched the number yesterday, the only information I could find was that the service provider was Time Warner Cable, which I found rather ironic.  If it continues, I may try contacting TWC about this particular number myself, since TWC is my service provider as well.  Maybe they can do something with it.

Call a lot, never leaves a message. Called back got there recording telling me what they do.

Ask for certain person then hangs up

I just got the call, they said "you sure are hard to get ahold of". Looks like they had called several times today. It was the American Cancer Society wanting donations to help women get services like mammograms.

My call seems to be coming from a different source than indicated above.  I guess it is a spoof. A msg. was left from Cardholders  & to return call if I wanted to reduce my credit card rate. As per usual: "This will be their final notice." Yeah...right! I wish it would be! They used to spoof my telephone number so my own telephone number appeared on my caller ID. Can't seem to do anything but block another number!
