no ip gain

Ive played 3 matches today and gained no ip for them, when altogether i should have gained between 700-800 ip. I have noticed something was wrong after the first match, when i gained 479ip and my ip from before never changed but i ignored that and thaught it would show up within an hour but no, so far im 3 matches in today and was trying to save up ip for a new champion and currently have 1 ip boost left on my name so i shall stop playing untill the problem is resolved. if anyone has any idea how to fix the problem please comment soon. sincerely, Tom a.k.a. tuck2135
