剛剛收到10月2日至6日的帳單, 為何這個月總共收到3次帳單呢? 以往都是每月發兩次帳單給我司的。下月是否會變回一個月發兩次呢?請盡快回覆, 謝謝!
We have received your bill for the period of October 2 to 6. We are baffled as to why you have sent us the bills three times this month, as it is different from your usual practice of sending us two bills in a month. We are eager to know if you will reinstate your normal practice next month. We look forward to your prompt reply. Thank you.

Note: I put the focus on making it a more formal business letter instead of a straight-forward translation.
