I want to report about referee wrong decision all the time

It would be good if you elaborate what you feel was wrong and if possible attach some evidence so that someone can take a look and advise mate.

Having said that there are lots of known issues - incorrect offsides, Awarding free kicks to the team who fouled opponent, Penalties unduly awarded etc.  If you want to help in improving things, then we need to provide some data so that EA can look into it.
