2) your explanations, and
3) your inquiries.

参考答案: Dear Sir/Madam,
I received my printed telephone bill of July yesterday. I very much regret to inform you that there is something wrong with the bill. I didn’t ask for the international call service, but there is a charge of BE Yuan on it. Besides, I couldn’t have made as many as more than B00 local calls last month. I would like to make clear what these dialed numbers are. Furthermore, I have never been late in paying the telephone bill, however, there is a A0 Yuan overdue fine.
Would you please offer me a detailed call list and call cost and check your system to find out what the problems are In the meantime, I shall keep this bill until I hear from you.
