Booted for scoring goals

Thought I'd do the assist objective when I needed 40 gls to complete , so I went on beginner squad battles and got the required 40 assists , ended the match and it spouted some nonsense about not being able to compete and booted me from the game, so objective not complete, tried again later on in the day and it did it again.

Clearly this is a deliberate and on purpose thing in the game so you can't complete objectives quickly, theres no way it isn't , it's yet another example of unscrupulous and disgraceful hidden practices in this game there's absolutely no doubt in my mind about that.
