No one spoke when I answered, then they finally did and said they were with the Southern Energy Group or some such name and wanted to come in my home to show me how to save energy. The caller repeatedly said they don't sell anything. I asked for a web site or literature and they said they did not have any, but their "technicians" have IDs. Beware.
Same problem here. VM is full when I call back. (Plus it goes right to VM when I call - does not even ring. Although this time when they called - I heard people, women / maybe girls talking in the background. Could not make out what they are saying... after 5-7 seconds, they hung up. (407) is a Orlando FL cell phone number.
