Talk about the effect

The customer didn't reply. These three sentences are absolutely explosive!

(1) nifty

Teacher Liu, every time I send you a message, I feel very uneasy, because I sent it to you, but you didn't reply to me. I am embarrassed. Don't send it You contacted me on your own initiative. You are embarrassed. I'll take the initiative to send it, but can you not make me so embarrassed?

(2) serious

Mr. Liu, I quite understand what you mean by not returning my messages. To put it bluntly, you haven't thought clearly about this matter, and I haven't sent you a message to force you to ask for the result. I just want to try my best to solve your problem, so if you have questions and concerns, I will continue if I can help you, and I won't say anything if I can't help you.

(3) Formal

Teacher Liu, I haven't called you for fear of disturbing your life. I chose to send a message in the hope that you can see my sincerity. Out of courtesy, I can't keep interrupting. As a salesman, I also hope to get your answer. I don't want you to know everything about me, but please tell me your answer.
