My game glitched causing a remake and a leaver buster low priority queue.

I'm pretty pissed about this, I started a ranked placement match and the loading screen was longer than normal, so then i realized that it was glitched, I tried to restart my client but it still wouldn't load. This eventually led up to my team remaking and causing me to get into a low priority queue.
