same info as Cyndi on 3/19 comment, however I held on line for about a minute and a woman came on line stating I did an energy research phone call survey a few months ago--that is true--and I "won" $3000. worth of certificates etc. She could hear me say un-huh and said was not a scam and need people to try out new health device air purification unit called SFS.  They just wanted us to use and report back to them on it. They would have a delivery man come and explain and then we are to review it.   Told them I was not interested and she said ok.  Thanked me for my time and we hung up.  I will report back here if anything else transpires with this.  Hopefully, I will not receive more calls regarding this.  I knew I shouldn't have answered the energy survey.  Oh well.

Received a call from this number saying to please call about a package delivery.  When I called, there was an automated message saying "if you're trying to reach the winners hotline, please press 1, if you received a call about a package delivery, please press 2, if you're calling about (couldn't make out) sweepstakes, please press 3.  I pressed 2, got music & a message saying I was 1st in line, then held & held...finally hung up.  Scammer??
