Mine had some odd, very minor, 10p's etc taken from it.
I am with Tesco CC and they rang me before I knew about it. I thought kids might have purchased something moody, but it was as everybody described above.
I have nowt but praise for Tesco CC. Whenever a strange transaction registers on my account, or a transaction takes place from a strange location they are on the moby like a shot. I was buying wine in France once, and my card was refused in the shop. Next second, call from Tesco, are you in France / are you Mr Price etc...ok we'll authorise payment. Brilliant.
I guess its fairly simple with me though, if some sap trys to buy Moet on my card when the regular tipple is nothing less than Bollinger then alarm bells ring.
I had another card cloned in Sardinia once. Tesco again, and I had a number of largish bills at a local bar etc. All refunded when I proved innocence etc. The eyeties also tried to buy £4000 of carpet / bathroom tiles etc. Card refused. However, the shops know its going on cos they would still keep the money!
And the blighters want to get rid of cash. Mr Throttler, at 108 and still going strong, you must remember cash!
