Game will automatically stuck when I'm winning

I played solo contest hell mode final battel with 3 4 times and last times I'm getting win that match but game will automatically stuck. Nothing can happens I had tried so much I check my connect , switch my connection nothing works. this match gives me 8k solo contest points but this nonsense shits everytime disturbs me . I lost my time , game money , my props whos gave me back ? What I can do now ? I'm write a long review on your google play platform. You just money thieves nothing can you fix in this game . You take money and add new contests new superstars but not taking care of these games issues this worst thing I have ever seen in my life 😭 just fix my issue and tell me what I do now?
