Yep. This is a scam # 301-730-4800. They also left 800-825-0393. They are very smooth, wanting to talk about fraudulent charges on my card. When you call, they ask for your credit card #.
A female caller claiming to be from City Bank credit card department want to verify the information on my credit card request. I did not requested any credit card from any bank or any other type of card.
Very smooth talking, left a voice message claiming I need to call them back about my Citibank request and that they needed further information. I haven't made any requests to Citibank.
