Who called from 6472412510

Just received a phone call from this number on my work phone.  No message left.

this number just called me.  the message left on my phone was a recording about millions of americans getting debt relief on student loans

canada calling me, not leaving a number or any voicemail

I answered the call... It's to lower student loans,

My husband has been getting these calls for a few days now, guess it's my turn, they just called twice, no balls so no message.  If I don't recognize the number, I don't pick up.  And off to the blocked list they go!
