Hey i want to disable the commands of amx chat commands

amx_psay <name or #userid> <message> ADMIN_CHAT Sends a private message to a player.
amx_tsay <color> <message> ADMIN_CHAT Sends a left side HUD message to all players.
amx_csay <color> <message> ADMIN_CHAT Sends a center HUD message to all players.

i dont want anyone to use this commands so how can i disable these 3 commands??
