Matched in ranked on a team of 3 vs 4

Queued for solo/duo ranked and was put in on a team of 3 vs 4. Of this was unfair and there really wasn’t much of a way we could win since it was stronghold. Lost rank after the match. Can’t leave the match because that will make you lose rank too and/or get banned. Have to go through the whole match and waste the time as well.
