2 games that i have played didn't give me IP

I have played two normal game in 11 January, one with and anotherone with , so i got a penta with graves and when i won the game, i can't enter to the scoreboard, so i clicked skip, and than the whole page was freezes. then i have to relog again , when i enter my match history screen, they are all gone, and didn't give me the IP, i was really angry, that two games are my best games on 2015, i just coudn't Tolerate this........ so i hope riot restore the IP that i earned and restore that two matches in match history.
