Matches arent showing in match history

I played numerous games yesterday and none of them are showing up in my match history. Pretty simple problem, not sure how else i could expound on it. It's been doing it for a couple days now, either lagging and not updating for a while or never adding games at all. Biggest problem is, I'm afraid to play ranked and not getting credit like i did last time and you did nothing about it to help me even though the problem is with your software.
