I'm after some advice to see how this might have happened. I have a fairly new 0% interest credit card which I opened purely to transfer my balance to. I have never used my credit card to purchase something and never intend to. Today I was contacted my the bank to check if some transactions were me- I did call the bank direct to check this was genuine. I asked them how someone could have got hold of my card details if I have never used the card - so the only people who should have the details would be me and the bank but they couldn't help. Any ideas? I've had credit card fraud before but this has been on cards I have used online/in shops. It's horrible when this happens and makes me feel so paranoid and worried
