Completely unacceptable rollback of DCd

So i worked and worked to get the maximum amount of this new season of datacrons, spent loads of crystals, in game currancy and some real money to get 30 level 9 dc's all with the correct level 6's etc etc, i was really happy with the work i had done to get what i wanted.
i just log in and now i have 30 level 5 dc's, no reroll mats refund, no crystals refund, no in game currancy refunded and no real money refunded 
and on top of that all the reroll costs are still at the max 
CG you are now seriously a laughing stock in game developers.... how can one compnay be this rubbish and get so much wrong... 
this needs fixing like NOW
