H2H win counted as a loss after inappropriate activity message

I have won a match in division rivals head to head 18-0 then after that match it is said that their is a inappropriate thing and considered it as a loss even if i won without any cheats.

Its pure unfair and i will stop playing and ask my friends also to stop playing 

So please fix this 

There is no evidence that i played improperly then why it is said like that and considered that match a loss
