I found out today that I have been charged £13.50 to Vue BSL for cinema tickets. We never go to the cinema. Also Tesco top up for mobile phone of £30 and other transactions, amounting in all to approx £700. My CC Company rang me today to tell me because one attempted purchase was made for £500 and the three digit security code was not submitted, which is how the Bank noticed it, and have refunded without delay. I think this 3 digit code should be required on ALL internet payments as it obviously works. This is the second time I have had to change my card number in less than 12 months for the same reason and I am seriously considering phoning in the number for purchases, rather than putting them on the PC.
