i am not receive any grade in my three game

i had that way more often. sadly most of the time when i had really good games which couldve gone even s rank with chest (for example a 5/0/18 taric game). Sadly the support isnt really helping and u dont get score or chest (if s rank) later on. They just say its a server problem and u see it on the server status page (error wasnt listed there by the way) and i should check internet connecting and so on (is good at my place) and the "normal stuff" (which was all not the case). But actually it seems like the problem lies with riot and just isnt getting fixed. [sg-janna]

I just got this as well on an ARAM where I went 12/9/21 on Tahm, I'd hope for an S (althought maybe not) but got nothing. Will I be graded for that or is that grade gone?
