Riot Blocks me from Que even though it's their fault

Recently I tried to play a normal draft pick game and after banning out our champs I went to lock in a champion but League said there was an error locking in my champion. After that it said I left the champion Que and I was blocked for a certain amount of time. This happened to me a total of 3 times and I reported it as a bug 3 times yet riot didn't do anything about it. All you GAMERS lemme know if this happened to you.
