Cheater In my Fleet Arena

For the past week there’s been a cheater getting rank 1 in my fleet  arena shard with a 2 star executrix and 4 star ships, going up again Leviathans, profundity’s and executors. I reported him in game when he first appeared but he’s not banned yet, and I’ve lost rank 1 rewards a couple times when he attacked me last second before payouts. His ally code is 261591816, and his swgoh.gg profile is https://swgoh.gg/p/261591816/ and bellow is a screenshot of proof of the fleet he’s using. is there another way I can report him so he finally gets banned.
