Is it:
I don't understand you at all.
or
I don't understand what you say.
?
And you is plural or singular?

It is:
I don't understand what you say.
"you" is singular.
おっしゃる is the honorific word of 言う.

Uhm so "I don't understand you at all." should be unlinked?

I think so.

Done :) please translate 252797 into Japanese or whatever else.
