Lost an FC mobile match after i won my opponent

Dear FC Mobile

I was playing a match recently against a player named King-skado in fc mobile head-to-head, 

once the game started the player disconnected but i kept playing regardless and won 4 - 0,

when the game was done i realized that i lost 2 - 0 and i checked my opponents profile and head-to-head history and then i realized he had won all his last visible matches buy 2-0 also,

so this begs the question.....is he hacking? 

if so can you people fix this?
