Never say “said me”. 
Use “told me” instead.

Don’t say: 
– My boss said me, “You need to work tomorrow.”
– My mother said me I should get a haircut.
– Isabella said me she will be home at 6:00.

Say this:
– My boss told me, “You need to work tomorrow.”
– My mother told me I should get a haircut.
– Isabella told me she will be home at 6:00.

Remember:
…told [who]…
He told [ me / her / Maria / his son / the man ] to go home.

…said [what]…
He said, “Go home.”
My mother said (not said me) I should get a haircut.
