Win counts as loss due to server problem and coin penalty on top

A few minutes ago i played two rivals games. 

In the first one i lead 3:0 in the first half. 

The opponent quits, my game freezes and when i connected again i lost the game and got a coin penalty message on top. 

I won the second game 5:3 and the opponent didn't quit. With the final whistle a Server connection message occured and back in the main menue i got the same coin penalty message as in the first game. Of course the win didn't count. 

It is very frustrating as i have a hard time winning in this game and when i win the Server connection will take it away ☹️
