Call people who don't reply to messages.

It should be polite and friendly to call people who don't reply to messages. If you send someone a message, but they don't reply, you can choose to try to contact them by phone. The following is a reference to ask the other party: "Hello, I'm XXX (your name). We contacted before, but the message I sent you has never been answered. I want to ask, have you received my message? If it is convenient, can you give me a reply or explain the reason? " When using this way of speaking, you need to pay attention to your tone, be polite and friendly, and respect each other's time and privacy. If the other party can't reply to your message for some personal reasons, you should also respect the other party's decision and provide some help or support to enhance mutual trust and understanding.
