Dumb Glitch (getting annoyed) -_-

So.. i have been playing games when i lag out for a second because league randomly says reconnecting even though my wifi is fine. I have been lagged out for 2 minutes and it says I actually was a afk troll so now i have a 20 minute ban for 5 games. I have been through 2 of these Low priority. This game i just played was my promo to bronze 2 and we were wining.. i lag out for a second then back in my team surrenders for no reason and boom im now at 5 games of low priority when i just finished the last 5.. This is really getting me frustrated! Please take it off ofme or do something!!!
