LaLiga president Javier Tebas has responded to Vini Jr's complaints after he was sent off on Sunday at Valencia.
Los Che won 1-0 thanks to Diego Lopez's goal as Vini Jr was sent off late on and subject of racist chants from the home support.
Vini Jr later accused LaLiga of ignoring the abuse.
Tebas said: "Because those who should do it, don't explain to you what the Liga does in these cases, we have tried to explain it to you, but you have not shown up for any of the appointments that you yourself had requested.
"Before criticising and insulting LaLiga, it is necessary that you inform yourself properly.
"Don't let yourself be manipulated and make sure you fully understand each other's skills and the work we've done together."
