收到答覆投訴的英文信,如何用英文回應?

-------Model Reply to 2nd Complaint--------
Dear Sir,
-----Thanks for your reply email in English of complaint of Jan1st,2013 offering me an apology for future improvement in your Hotel which I've accepted.
-----You appear to have been too optimistic of the good manners by your room-cleaners and servicemen in Room No. (xxxx).
-----Secondly the impoliteness of restaurant waiters and waitress would be difficult to manage for a better servicing in the English Cafe (xxx).
------Obviously your reply is a general one merely diverting the truth without any "improvement methods."
------Please accept other Guests of Honour's opinions and to answer what their complaints are by a thorough piece of investigation, because we had been unfairly treated and suffered on Jan1st.
-----I think you'll see the complaint likely to raise to a higher level to the HK Govt. if you don't investigate thoroughly.Your managerial connections should enable you to solve our complaints and make your Hotel Buz more successful.
-----Thank you for your time and Energy to read the second complaint email.

Yours sincerely,

咁情況都特別的 :)

我第一封信好長,所以是中文,之後佢SEND中文MAIL詢問我詳細"發生日期,房間號碼",咁因為簡單所以我用英文答覆,最後收到的正式REPLY便是英文了

不過你也正確,因為我確實第一封投訴信是用中文寫,亦應該是收到中文回應,多謝你的提醒!

咁你第一封email 去信時係用中文或英文？
如果用中文的話，他們必須用回中文回覆。否則不禮的不是你而是酒店。
