Playtika — slotomania rapid cats game

I completed my free spins on this game and my win total was over 900, 000, 000 and when I had completed them my coins total only went up by just over 120, 000, 000 so I would like the remainder of my winnings credited to me please.
I have attached a screenshot of the final result of my free spins to show you that my complaint is valid.
As a player of some 8 years standing and level 20840 i feel that this complaint should recieve your attention and ultimate rectification
