opponent made me dnf

in cahmps i was winning 6-3 on the 80th minute and the opponent paused, theb after 30 secs he quit and i was transferred to the page where i get awarded the match coins but immidiately i get disconected from the serversand when i get back to ultimate team i have received a dnf and  the match didnt count for the laliga 15 ganes objective. I believe that my opponent caused the disconect but i cannot do anything about it
