Who called from 3472548166

Called twice. Left no messages.  If you can't leave a message, then it's not that important. BLOCKED!!!   >=^)

When I tried to call them back it says "the number you called is incorrect" BLOCKED!

claims to have been monitoring my credit usage and would save me money if I have a balance of $10000 or more .  9 to talk to a person .. that was it.

I had a similar experience as noted above.
The good news is I did not get a fail delivery when I sent the following text message:
Dear phone solicitor,
go to the nearest street corner and hold a sign.

Did not answer. No msg left. Immediately another call came in with Florida prefix so was sure it was a scam.  The follow-up calls seem to becoming the standard.
