Who called from 3156366709

I have received several calls from this # at least 2 times daily for the last 3 days and they never leave a message; I feel as though it may be a scam if I answer.

Same as others........4 rings & never a msg.   Just static if you answer it by mistake!

do not call

They won't stop calling.and they won't talk or leave a message.

if you ordered diet pills from they are calling to get you to order more I have told them twice do not call my number
