Hextech chest drop bugged

I tried to report this through a support ticket since I was struggling a few days ago to get a chest. I finished a bunch of games with an S on eligible champions, but not until several games of this did a chest actually drop. When I tried to make a ticket, the guy assigned to it tried to tell me it was something to do with me receiving a chat restriction when I was currently Honor 1 (unlocked, I had just finished a chat restriction from a few days ago) Just curious to see if anyone else is having this issue.
