Boss glitch and score delay

I played a warzone game on raid on apex and I was winning 998 to 800 and something with two bases captured. A Grunt meck spawned and when the score reached 998 the score stayed there for 4 seconds and did not increase, the grunt boss is very hard to kill and when it was at mid health after 4 seconds at 998 the game ends saying defeat. Somehow the boss kill was awarded to the other team and the boss didn’t even die. Can someone plz fix this issue or glitch. I just received a bs loss on a match I should have won. This loss should be reversed and I and my team should be awarded the win. This glitch on the grunt boss is ongoing and need to be fix and ow there is a score delay. Not fair at all. Please change this loss to a win because someone from the other team exploited a glitch and used it against us. Please help this is considered an incident report.
