Robbed of an S

For the past few weeks me and my friend have been trying to get Draven his last S or S+. We FINALY got it last night and as we happily clicked on the loot we thought it had given us, come to find we never got anything for it... Now I understand this may be a bug or a glitch that's yet to be fixed, but grinding games just to be robbed is NOT what either of us want league to be about. All I'm asking is for that one S to actually mean something, and to please give that damn mastery 7 token that we worked so hard for back to us.. Other then that I f**king love this game!
