[单项选择]From: Fiona Parsons To: Jerome Patel Subject: Delivery Dear Mr. Patel, Thank you for calling me to let me know that the building supplies you ordered have not yet arrived. I’m sorry for this delay, and I hope it does not cause you too much inconvenience. I was very surprised to hear the message you left on my voicemail this morning. I called the delivery company immediately afterwards and spoke to a representative there. She said that a mechanical fauh with one of the trucks has caused a backlog, and she promised that your delivery would be made top priority. They expect to get the supplies to you by this afternoon. If the delivery does not arrive by the end of the day, please inform me so I can follow up on the matter once again. At Online Building Depot, we pride ourselves on our excellent customer service. So, as a result of this problem, we would like to offer you compensation to show that you are a valued customer. I suggest that the delivery fee be waived A. Straight after Mr. Patel made the order B. Before speaking to the supplier C. Sometime after the due shipping date D. Before signing off on the delivery
