Beware of fraud calls from Citibank

I got a call from a lady saying she is a Citibank employee(Shyla) and whether I am interested in Citibank life time credit card. I was getting these calls many times and every time, I told them I am not interested. This time, she told me that they are giving credit card and DVD player as diwali gift and they want to know my address. I talked to many people regarding this, and they said "Go on and get it. Later you can cancel the card". I thought, it might be possible as I have seen some "get a watch by applying for credit card" in Citibank online site. So, I said "Yes". Now, recently, I got a courier for Citibank credit card and I didn't get the gift that she promised!!. I called her up (Fortunately, I had her number with me) and asked her regarding this. She said " It is in pending status. I will let you know after checking why it is in pending status". I still thought she is telling truth. Next day, when I called her up, now she started acting. She said "It is a wrong number. She is not the one whom I called". I thought "May be, her number might have changed. (Though it is less probable as I just spoke to her one day before)". I made a call to her thru my friend and confirmed her number hasn't changed. Now, I called up Citibank and told them this is what happened. Finally, it took so much time for me to cancel this card.

Moral of the story: Beware of such fraud calls rather wasting time and money later.
