Ranked Flex

So, I was playing a ranked flex as Zac top and 20 minutes in we are winning our lanes, for the most part, and on the way to an easy win. I am about 5/0/9 (not sure about the kills and assists, but 100% sure on 0 deaths) and we are pushing mid to the 2nd tower. 35 minutes in our Shyvana goes AFK and what we thought was an easy win turns out to be an almost 1 hour game with the enemy team coming back, obviously taking advantage of the 4v5. Would it be possible for another game to replace that? I understand that the other team could have had an AFK too, or maybe Shyvana was having problems in real life, such as internet connections (which I have too) but I would greatly appreciate it if I could redo just that one game. Thank you very much for listening to my opinion and I hope you have a great day. And thank you Riot for making this game, even though it's not perfect it's still something I find myself coming back to time after time.
