I was contacted via phone - the person claimed to be a Citibank representative and said that they called me to lower the interest rate on my credit card. They asked about my phone number, type of my Credit Card, my CC number and the expiry datye of the CC. They asked me to confirm the last XXXX digits of my SS number. I suspect this might have been a scam and the info they obtained could be used to purchase goods. I would like to ask for verification.
