I just recieved the same call. Hit "1", said it was for my credit card, i asked which one, he said visa.. by the way, not an american accent. I asked which visa, he said it's either Chase or Bank of America. Hmmm. He started asking me about my account and my balance. I told him i do not do any business over the phone and to mail me the information. He hung up. Shady shady shady ... reporting the number now.
Same number called at 11:43am PST
I did not answer since it came up with WI USA on the caller ID.
I suspect it is the same as otherhave stated here......potential scam asking to verify credit card information.
