Who called from 3479258858

I keep getting these phone calls from this number I would like them to stop.
I will not answer no one unless I know who it is.

This number keeps sending me text messages to loan me money. I have sent the "STOP" reply several times but they still send me a text to my cell almost daily. They should be reported to the FCC.
