Who called from 5042737984

Someone from this number has called several times in the last couple of days. Hangs up when you answer, leaves no message.

I keep getting calls from this number too.  I never answer.  Not sure who it is.

Received several calls from this number in the last few days.  No one answers when I pickup.

I get multiple calls a day. I have called back and asked to be taken off the list but they have not done so. What can be done?

No one spoke when I answered.  Called number back and it is for the Houston Chronicle
