Who called from 8018397758

I received 2 calls today from this number. Missed calls. I tried to call back and recording advised it is disconnected. I tried again thinking i missed dialed and recording advised " I have reached a non working number. I get calls from this number at least 1x a week. for the last 2 months. No message is ever left.

i was at a truck show and signed up to "win a free ipad" I knew it was probably an info collecting scam but I just dont answer it. I am sure I didnt win an ipad!! haha

they called me last week and just today, have never left a msg

they called me twice today. again. leaving no msg

got the same thing. called back, got busy signal every time
