The infamous Lower your credit card rate scam has spoofed this 'wireless' number from Alaska.

My answering machine caught part of their robo call message to press 9 if I wanted to speak to a rep.
With no response, they hung up.

Calling this a prank. I actually tried to report it to another web site but an odd thing happened a page came up in Asian characters that when translated basically said I couldn't leave my comment because it contained a message that wasn't legal. The same message I have here.
So now you know it really is bogus.
