[填空题]Dear Sirs,
I am writing to confirm the loss of my credit card. I telephoned your office earlier today.
The details of my card are as follows. It is an Apex Silver card in the name of Paul Anderson. The credit card number is 5431 752 247 8431. I have had an Apex card since 1994. This card is valid from August 2003 to August 2005.
I lost the card yesterday at about 8: 30 in the evening. The only case I used the card yesterday was to buy three dictionaries at the Dillons Bookstore in Oxford Street. By accident, I left the card at the shop. When I realized what I had done, I telephoned the shop, but the shop assistants there could not find the card.
Could you please cancel my card immediately and make the necessary arrangements to issue a replacement card to me I can be contacted at the telephone number of 347-437-901.
Thank you for your assistance.
Yours faithfully,
