Ban people who ruin Odyssey for once, Riot

I just want to play Odyssey on Onslaught, but every single time I try to play the mode I get atleast one troll and 3 people wanting to surrender instantly only because others didn't agree to carry them for their missions. It's rather sickening. I know that it's not the main mode, but how does this behaviour go unpunished? They're simply ruining the mode with their childish behaviour. They expect random people to do as they want.

Please Riot, start punishing these griefers
