I left a lot of messages for an uncle's net friend, but he ignored me. What's the matter, but you won't delete me?

This can be divided into many situations.

In one case, he was busy recently and didn't have time to surf the Internet at all, so he didn't see your message and ignored you.

There is another situation where you don't know each other at all, and he doesn't think it is necessary to talk to you. There is no such relationship between you.

You ask him questions, but he doesn't want to answer them. After all, there is no help for no reason.

There are many, you should first analyze the reasons from your relationship.
