Who called from 7128288823

I missed the call. They left no message.

I let it ring and they left no msg.

Same here.  Let it ring and they left no message

Same as the others.  Hopefully, I didn't make a mistake, blocked my phone # and called back.  It was answered w a recorded "press 9 to be put on the do not call list".  I hung up.  Don't know anything about cell phone phishing, but is it possible that by pressing 9, one would be doing the same thing as clicking on a phishing link in an email.

no answer
