I go by Nina as well...I've received several calls from this number. Never leaves a message and never says anything when I answer. I wonder if it's one of those smartphone hack attempts? Good thing I don't have a smart phone!
This number just called me at 6:20 in the morning! my heart stops when my phone rings that early. i think one of my kids is hurt. that is not during normal business hours amd it looks like a business number so of course i answered it. im extremely angry!!
