I can't understand when I write to the teachers asking if they can teach to a person what don´t know speak english very well,and they don´t answer me! :(

Hi, I'm not a native English speaker, but I've spotted some mistakes. 

To teachers - better without "the" if you mean teachers in general

To teach a person - without "to"

A person who (or "that" - informal, but not "what") doesn't speak English very well

Examples with what and that:

I received the letter that you sent me.

I don't understand what you mean. 

So, here is what we've got.

I can't understand why, when I write to teachers asking if they can teach a person who doesn't speak English very well, they don't answer me.
