Leaver status undeserved

Hi,
I have leaver status while I never left any game…
In last ranked preparation screen, I was pre-picking raynor. Then when the last countdown was about to end (for the choice of last heroes) a teammate chose raynor too and that canceled directly the game like if someone left. I did not leave but since that, I have the leaver status… Can you correct that problem please ? The game says I am going to be matched with other leavers and cannot play ranked :’( This is so unfair, please make it so that this don’t happen again.
