Dear Jack Martinez,
I am writing to inform you that my credit card bill just arrived today. Upon checking the details, though, I noticed that there is a charge in my account for an item which I have never purchased. If I am not mistaken, this transaction took place during the time when I reported my card as missing. I was assured that my card was already blocked at that time.
Could you kindly look into this matter and make sure that the necessary corrections are made to my account? Should you have any questions, I may be reached at 434-3434 during office hours. Thank you very much for your assistance!
Sincerely,
Lukas
