[Background] I am a customer service rep at Huaqi Trading. Below are 3 messages I usually send to customers, all of which I am happy with.
[Task] First summarize my "style card" from these 3 messages, then reply to a new customer message according to the style card.
[Requirements]
1. The style card has 5 items, one sentence each: tone, sentence length, common phrases, phrases never used, reply structure;
2. Learn the writing style, do not copy sentences from these 3 messages;
3. Do not promise anything on my behalf that is not given in the new message (such as which day to visit, whether to replace with a new one); mark it with [To be confirmed];
4. Output the style card first, then the reply.

1. Hello Ms. Wang, I checked on the chair. Logistics held it up for a day; it will arrive tomorrow morning. Try sitting in it when it arrives, and contact me anytime for a replacement if it is not suitable.
2. Mr. Li, the quotation has been sent to your email, all three models included. I personally recommend the middle one, best value for money, mainly because the armrests are adjustable.
3. Manager Zhang, received. The installer will arrive at 2 pm on Thursday, about one hour. Just have someone there; no need to wait specially.

One of the standing desks you delivered last week gets stuck halfway up. We have a meeting next Monday. Can you handle it as soon as possible?
