How to prove my task complete?

I dont know how to prove my first task (five match played). The statistic page on my profile, doesnt show my name, if i send that picture i will be rejected. Please Help me how to prove it. I finished the task within the time and i think its unfair for not informing your users enough how to do it right. In my last 3 day every of my submitted task rejected. Most of them because you dont provide information what you exactly want to see.

20min and the task bonus reward are unavailable.
Shame on you little witch....
