Game kept disconnecting, team reported me and now I have 20 min queue penalty

I'm living in a college dormitory right now where we recently just got a new ISP, the connection is newly set up and shared among all of us who lives here.

Usually when it's day time when people are out and about, the connection works perfectly fine, but sometimes even during the day my roommates are watching movies or using the internet, the wifi signal can get extremely bad and I end up with literally 1-2k ping in a game, making it essentially unplayable.

My game also keeps on getting disconnected by that point and stayed at the "Reconnecting" screen, in which case I have to manually exit the game, sometimes reset the router in the common room (risk pissing off my roommates), and relog into the game.

Sometimes it works, and I get around 100-200 ping which makes it somewhat playable, sometimes it doesn't work and I'm just stuck with disconnecting and reconnecting all game.

A duo queue from last game got pissed off that I had to disconnect and reconnect so many times, leaving them to fight 4 vs. 5. It was never my intention to abandon the game, my connection is something completely outside of my control and I even showed them that my ping is literally 1-2k, and there was nothing I could possibly do to fix it in the mean time.

But they reported me for "going afk" and "leaving the game" anyways, and now I have a 20 minute queue penalty.

How is this fair.....? Are we going to punish people now for factors completely outside of their control? If my house suddenly catches fire and I have to leave a game and my team reports me, am I going to get punished?

If a local powerline gets hit by a lightning and my PC loses power mid way through a game and my team reports me for suddenly disconnecting from the game, and I going to get punished?

I wish to have an official Riot response from this.
