Unfair Declaration of Result by chessdotcom

When I  was playing whites and the opponent playing blacks, black has been declared winner of the game, saying game abandoned. I did not abandon the game. How come the result say like that. In fact I am in advantageous position with 26 minutes left in the 30 minute game and the blacks have 14 minutes left. It was the turn of black to make a move and no move was made but a result was declared saying black won. Either the site chessdotcom has technical snags, or it has a ridiuclous software and that software is vulnerable for playing tricks like this. I need an answer for this from the site administrators.
