I believe you have a valid case here.
FIFA rules dictate that a match cannot be played only when opponent has fewer than 7 players.

In case of 10 vs 11, the match should have been played and not a direct 3-0 forfeit.
That being said, I am not aware if Top Eleven rules are different in this regard.
If they are, they should be changed to prevent situations like yours
