I was going to answer just to provide a better feedback here. But, after searching on Whitepages.com (http://www.whitepages.com/phone/1-321-430-9649) this number has been flagged not only as spam but as a "High level Scam & Fraud". I searched for their website but most of the pages are broken links http://brightenergysolar.com/contact-us/ and there's a person complaining on their Facebook page as well.
Received 3 calls in a row this morning. Answered 2, but no one there. Call just dropped/hung up. Blocking call now. It only showed the phone # on the caller ID.
