请帮我翻译一封信

我加你，可是不能留号

回信如下：
Dear Sir or Madam:

I feel shaken up and so sad to receive the letter below.

Sorry that I really do not know the Online Trading Activities can be lead to Account Cancellation, I just want to buy the prop online and to be more stronger in the game. It takes me lots of time and energy on this game, and now I am already rank 60. Please, Sir, could you please forgive me this time? I guarantee that I won’t make this mistake again in the future.

Your kindly attention for my mail will be highly appreciated.

Best wishes,

。。。（NAME）
