Why did i loose all my req points?

I had played to get 1 million req points and I did and I went to buy my 100 gold packs when I bought one my req store crashed and said error so I went back to the req store to see all my 1 million req points gone and on the bottom right corner of it saying 1,000,000 req points it said 684

That sucks but i have no idea how to fix this sorry. :frowning:
