Banned for coliseum glitch

Within an hour of this new era releasing, I was going through testing the best teams. My loaned units were at level 18. Not knowing this was any sort of glitch or bug, I continued with one team to complete tier 1. I woke up this morning and found my account banned. I don’t believe this is a fair ban as this is a new loaned units system that will naturally have bugs and glitches. With no information about how the units will be leveled, I did not know the level 18 units were not supposed to be that.  I have never broken any rules or terms of service in the past. Any support would be greatly appreciated. My ally code is 213-252-651
