Cant log in ...

Hello, I met a problem, I was in a match somewhere on the 10th or 15th minute and my wifi stopped,I restarted the wifi and closed the game and I started it again, I put my name and password correctly and I went in, I went out, I went in, I changed the region and for 20 to 30 minutes he did not want to let me in, I pressed enter 100 times in and nothing happened, after 20 minutes, I went into the game, I went in, I reconnected and after I entered the game the enemies were at nexus, I lost and I took 20 minutes for 5 games, I am angry that I have solved the problem with the wifi in 2 minutes, but for 20 minutes I could not and did not let me connect, and because of that I took the ban, not because of me ... can I cancel the 5 matches because it is not correct.I say once again , I was not able to conect into my account for 20 minutes , i dont know why , i record the error ! BTW, I'm sorry for what I wrote, I'm Roman!
