Caller said said he was from Dominion Gas. He said I was elegible to get a lower Gas Service rate.  Then he asked me to read him my account number.  I put him off by saying I was not in my house at the moment and did not have access to my bill.

Received a call on my cell phone and when I answered the person hung up without saying anything. I called the number back and recording not in service .
