As an Expert in Business Communication,you Realize That the Following

As an expert in business communication,you realize that the following closing line in Roza's message is not likely to be effective: "I want my money to be returned at the earliest.I have bought several products from Kian in the past but will not do so again if this matter is not resolved satisfactorily." Which of the following statements would best replace these lines?

A) Please resolve this issue at the earliest. Also, please keep in mind that I will no longer shop at Kian if this issue is not resolved satisfactorily.
B) I would appreciate a complete refund of my money for this product or a voucher for the same amount. I have bought several pieces from Kian in the past and enjoy your modern and functional designs and excellent customer service.
C) I did enjoy shopping at Kian and your modern and functional designs. However, whether or not I continue shopping from your stores depends on how you respond to my request.
D) I expect a full and complete refund or voucher for the price of the bookcase that I recently bought. Considering that it broke during assembly and is now useless to me, don't you think that my request is only fair?
E) Please give me complete refund of my money or a voucher for the same amount. Otherwise, I'll just have to take my business somewhere else next time.
