unacceptable foul

Today I was watching a football game and watch one of the most horrible fouls I've ever seen and also the player did not have any punishment.

in the party Barcelona V / S real Madrid and I saw  Sergio Ramos one of the best defenders in the world hit   Lionel Messi in his face with a flying kick trying to stop a possible goal, the foul should have been a direct red card, but the referee very strangely did not see the kick and also gave Messi yellow card for insist that if had been foul.

I think the player and the referee should be suspended and  fifa should view the video and suspend both for a time.
