Hi Robert, I really appreciate all the help you've given me. Your explanations are very useful. Thanks so much See you

Dear Sir or Madam, I am writing in reply to a bank statement which reports purchases on my credit card. However, I want to clarify that I did not use my credit card in that period. I have had the bank account (number 123456) in your agency since 2016. I also want to explain that I have never had any kind of problem with your services. I would like to inform you that I did not buy the listed things that you have reported in the above mentioned report because I was working abroad in that period. Furthermore, I would like to highlight that during the same period, I had used the debit card that your agency gave me in Berlin. I would suggest you to check my debit account - where you can find a complete list of the purchases I made in Germany. As you can surely confirm that I was in Berlin in April, I ask you for a refund of all credit card expenses. I thank you in advance and I look forward to receiving your reply as soon as possible. Yours faithfully, Peter Parker --- The initial sentence makes it seem like you did use the credit card last April. Changed it for confusion. Restating your name in the second paragraph seems off - usually people read who is writing a letter before they read the letter itself. Your English is pretty good, but if I were you, I would use less pre-set phrases. I think you might be using terms like "therefore", "furthermore", etc. a bit too often. The passage also could use a clarification of the Berlin trip in the first paragraph or so. Make sure that they know why you didn't purchase anything in the first couple lines. One last thing - a credit card assigned to me by my bank is (my) card. The agency can't usually take it away, so in English, it's (my), (your), or (their) card. Nice job! Your English is pretty good, again.
