A rank bug

Dear riot stuffs: I have lost more than 150 points because of this bug. I can queen up and in champion select. And there has no any lag when i am in game. By the way, my internet is good and my computer is connected by cable. But when in my champion selection interface, the number of champion selection stopped at 0, and it will never changed again . I can not do banning and picking when this situation happened, but i can still chat with friend in the client. Nothing will change till i close the client. I can not close the client with Upper right corner fork. I have to use other way to close it. It happened once a day In the beginning of the first week. Later became a day two to three times. Now every time I enter the champion selection interface when it is dropped, 4 times in a row. This situation let me directly lost a few points. By the way, I played my friend account on the same computer. Did not appear that situation, all normal. I lived with my friend in a house, and he never happened that situation. So, I think this is a bug about my account. I have emailed to riot. They replayed me here and told me u guys will try to fix this for me. If you have a solution or have already solved this problem, please reply to the email address: [email protected] Thank you for reading. Have a good day.
