weekly challenge problem

Hi guys can you point me in right direction of someone I can contact. Or give advice.

I’ve just completed the weekly challenge for 50 wins. But the credits don’t seem to have been credited to me at the end of the match it didn’t show the challenges. Only when I went back to the lobby did it recognise and pop up that I completed the challenge. But I check my rank bar and it’s in exactly the same place.

So I’m little bit unsure who to contact to have it checked out. Or if there is some way of checking how much last credits were awarded to me.

Also has anyone else had same problem.

Thank you.
