Who called from 7042200638

I have received a call on my cell phone every week from this number for the past 8 weeks. I have never answered and no message is left. Who is this?!?!

The same with me today.  This number called my cell phone and after saying hello twice, it/they hung up.  Shows as an unpublished land line in Monroe, N.C.

received a call   did not pick up

The call originates from a boiler room scammer working for a credit repair company out of Dallas.

how did you find this out? i am just curious because i got the same call. thanks
