My IP is super bugged :/

I had about 1735 IP and after i played a normal game of the rift i noticed that it had fallen to 600 IP :(. And i now have 1779 and i can't even buy the 1350 champions because " I don't have enough RP/IP" I did wait about a week or more for this to change but I've had no luck. Help me out Pleasseeee
