Something wrong with your payments system
Made a purchase and it was delivered super-fast, thank you! However, since then, more than $4,000 of unauthorised charges have been made on my credit card. Now, the reason I can point to you is that this transaction is the only one I have legitimately made on that card in months, and the fraudulent transactions started within a few days of use of the card. I am so pleased I didn't use my normal card, and the one with which I have so many payment authorities set up, to make this purchase. You need to change your payment vendor in a hurry and tidy up your accounting.
