Game Freeze- Ranked Season/Events

[jnr16924_PSN]

Every time I am in my way towards accomplishing a ranked season reward or winning a streak reward in events my game freezes and it stays that was and i end up loosing the game (while I was winning all of the games). This is already the 4th time that it has happen to me in which it doesnt help me win my rewards and it doesn't help my overall record.
