Problem occured – Cover Beauty Review

I was on level 4 and then one day when I was doing the photo shoots, it was unlimited. And so therefore, I did a lot of them to buy the second model. After I reach about level 5, I had about enough money. However, when I bought the model, it went back to the home screen and when I tried to get back into the game, my money was gone. Only the amount before subtracted by the cost of the model which was 1500 coins. And the game shows that I haven't bought the model even though I spent money on it. T-T
