plz send help. Worst champ select ever

When you're about to demote and your champ select goes like this:

Your sup doesn't play sup or have any actual sup champs

Your adc locks in jg without telling u and say pick any adc and he will trade back.

Locks in xayah, jg: "vayne"

me: "sry i didnt see your text"

jg:"Im not trading xayah"

me: "why?"

Later on: Sup locks in ziggs.

"I thought u were going to sup, lux"-Sup

"No?"-mid

Goes into game

Jg: "I wonder why this guy refuses to lock in a champ i want"

me:"???"

later on:

me: "Ziggs plz stop taking cs I want a farm lane, I don't think we can out trade janna cait early."

Ziggs:" no"

Proceeds to take cs

This got repeated for 20 min then he went mid

mid: "Ziggs plz stop, you're just leeching xp and gold at this point"

sup: "I need gold"

Rest of the game, jg and sup just flames me nonstop. I nearly wanted to afk but then my top and mid managed to convince me to stay.

Im not going to point out the names, but I crsly hope riot punish these 2 players because that's just some abusive behavior.
