A formal letter "missing bank card"

Dear Sir / Madam,

I am writing in connection with a missing or stolen credit card, provided by Algeria Gulf Bank and delivered from bank's head office to client account number 32548574 14. tThis is an urgent letter concerning my the new bank card related to my account number that was sent by the bank.

Yesterday, I received an envelope from the bank's head office in which is in the bay branch of Algiers, asking me to acknowledge receipt of my new bank card. However, after I had read all of the details and I discovered that there is was no credit card attached. More importantly, I checked the envelope and the mail box several times and discovered that the bottom of the envelope had been tampered with, indicating that the card had perhaps been stolen.  realized a tattered state on the bottom of the envelope. I suppose someone had stolen my card.

For this reason I request that am asking you to cancel my new credit card immediately, before they use it to spend my money if it is taken by the wrong hands. After canceling my card, please, and send me a new one as soon as possible.  because I need to use it abroad this week.

Thank you kindly in advance,

Yours faithfully,
Mr. Ahmed

Mr Ahmed, the corrections I suggest are minor, your letter is quite clear.  I have also suggested deleting some of the details that a bank would not require.  Also, credit cards cannot be used until they are activated by the correct owner so your credit should be safe.  Good luck  حظ سعيد
