I answered for the fun of it and it was a woman with a southern U.S accent. She said it was visa I asked how do I know this is really visa. She called me MR."my last name" then asked me if I carried a balance on my credit cards. I said why don't you tell me. She asked me again if I had a balance and when I said don't know she hung up
Called 3 times in a row, back to back. Second time came up long distance private caller, but I'm sure it was likely the same people. Didn't answer the phone, and they didn't leave a message.
