final score changed

Dear respective team
This is first time happened to me and I believe the cheats is exist only in real life not in website game.
I was playing match and the score ends with 3-3 and it was fine because I have won the first match and it was enough to be qualified to the next stage
But I logged in after fifteen minutes and I was surprised that the score has been changed to 2-3 which means I disqualified from the cup
Could you please check that issue or other wise it's not the environment of fair play we used to enjoy
Awaiting your instant reply
Regards

A lot of people have complained about issues like this, allegedly it's some form of server issue ... it's pretty bad if it is, especially in situations like this.

Unfortunately, I think it'll fall on deaf ears.

So can I understand that I will get nothing and I should leave this useless game?
