My wife and I have been receiving the SMU 972-473-3558, to our land line for several months.  Message always says it concerns credit card, but no emergency and dial 1 to get connected or 2 and they will not call again. Never did 1 but the 2 did not make a difference .....they keep calling.  A - holes!  Need to find out a way to stop this.  Please let me know if anyone does!!

I got one too. no message when you call it back and get a busy signal

Isn't it weird how random these calls seem to be?  The only thing that I have in common with this seems to be the word Southern, as in Southern California.  Please keep in touch and let me know what you learn, if they try again.

Got call this morning on my cell phone.  Did not answer.   Then I noticed that they tried to FaceTime me!    I don't answer if I don't recognize the number.  

Thank goodness for Mr. Number. The best call blocking service out there. They block the calls,  then I can Google the number and see who or what they are. I don't even have to here the number ring through or have it interrupt my phone service. Mr. Number strangles it as soon as the number shows up.
