I have gotten 2 calls in one day from this number.  The first time they didn't even have my name right, so I hung up.  The second time, a different person was on the line, claimed they were an officer conducting an investigation and that I was being sued.  I talked to them a few minutes to see what they knew.  They did have my email address and said that I owed money on a loan that I took out over the internet.  I don't so I know they are a scam.  How they got my email address I don't know.  I told him that if he had that much information, then, they needed to send me something in writing and I hung up.  This is very similar to the same pitch that someone else was giving me a few weeks ago, but those calls had a California and/or Florida area code.  This area code is from Texas.
