I got one today, usually don't answer, but did, and when they asked for my electric bill account name I said why and she said "do you want a refund" and I saw "do you want to answer my question" and she hung up on me. I knew it was a scam.
This is the 3rd number these horrid people are using to scam me. Third one I had to block. Brian is right, they just change the last 2 numbers. It is so sad to be able to block and all they have to do is change the number. Ugh
They called me again.. Caller id shows 3019657833. I thought i had them blocked, but I guess they got around it by dropping the 1 from the beginning. They left no message. I just blocked them, hope it works now..
