Who called from 4847200424

Received a call at exactly 8:00 pm.  The woman asked for my husband (his name is on the cell phone account). When I asked who is calling, she repeated that she wanted to speak with my husband. I hung up!  I couldn't find any info on the phone number.

I received 2 calls today from this number but no message. I have no idea who they are.

I have received three calls in the last two days.  I don't pick-up & they don't leave a voicemail...creepy!!
