I would like to thank your company for alerting me to the fact that someone had attempted to use my credit card to order goods from your website. I had absolutely no idea that my card details had fallen into the wrong hands so your letter, whilst a shock, was very welcome as it enables me to take the necessary action to prevent this card being used elsewhere.
Your stringant security is to be congratulated and I am certainly very grateful for those measures you have in place.
