Get calls from this number, but don't answer.
They leave a very garbled message on the answering machine.....
something to do with credit cards, I think.... can't make it out

WARNING--BEWARE!!  These callers are   B I G   credit card criminals, known as the card service scammers. Under NO circumstances give your credit card number to these lowlifes, or you will regret it forever!

I guess they're posing as some type of company that will save you money on your electric bill, because it came up as "Energy Service" on my caller ID. I picked up and nobody said anything.

called and hung up, continues calling 3-4 times a day. harassment.....
