My teammates flamed our support and then he went afk

This is a pretty vague post

That's annoying. I usually don't have bad experiences, but last night I played with a 5-man. (4 friends and me...) Game1 - I go Veigar vs a Janna, unknown ADC. I generally like to bully passive supports. I told my team I can't support the Vayne well, but they said ok. Somehow Mid goes like 0-4, disconnects, and loses inner turret while we are still laning for first item. (Top also loses). Somehow I get blamed for the poor game.

Game2 - I tell them I only play supp. Offer Janna, Sona, etc. See I am vs a Draven. Different Vayne says like "pick anyone, pick Veigar" but was super quiet sounded was "just not veigar??" still don't know. Either way easy pokes and zone on Draven (who was 0-3-3 in lane) (still bad for 3 deaths). Mid dies in the first five minutes to ignite. Vayne eventually says we need to kill this Draven (<50%) so I flash stun and hit my skills, but Vayne couldn't close the gap so Voli kills me. Mid continues to die to Jg and Mid. I get blamed again. I also offered to dodge. A comp of Fizz and Shaco is just not pleasant. They said no.

Game3 - Someone again tries to take support. They talk about being on tilt. So I just left, was super late anyways.

I don't mind, I will try to play with them again sometime. Hopefully we can communicate better as a team. There are definitely ways I could have played better. But when Mid is going 0-4 both games don't blame the support. The sad part is we could have won both of those games (hence I could have played better). But when people are stacking the blame on you, it is tough. And they weren't communicating and acting like they wanted to win.
