Who called from 7048095085

I have gotten several calls from this number, most recently, 2 minutes ago.  There is never anyone on the other end.  Anybody know what the deal is???

Received 4 calls in last 2 days.  I left a message not to call and machine voice said that it would take 24 hours...wrong.  The call came from Denver, CO (704 809-5085).  Was told it was a commercial marketing firm.  Through web research found it may be from Life Alert.

I stand corrected, that is Denver, NC not CO.

I got this call several times on my mobile phone.No said anything on the other end. The last time I let it go to voicemail and no message was left.

Tired of this no one is ever on the other end.Please stop calling me!!!!!
