Who called from 8010997643

getting weekly calls from this number. no voice mails. they disconnect if I answer. if I try to call back it says the number is invalid

This number calls over & over again & don't know who they are

This has recently started happening to me.  They are calling twice a week.  I was hoping to find something about them online but have not yet.

Yep, same thing. I won't answer the call though but they keep calling me.

Answered and they said they were from some student loan agency.
