Banned for playing colisum

2 days ago, 13th January, I got a message in game saying I was banned for cheating in colisum. 

i cleared tier 6 and got to 10% on tier 7.  This happened when I used Maul hate fulled and Inquisitor Barris on the team. 
I have 4 era marquees at level 58 and 5 star.  Barris is level 58 and 4 star.  Maul is level 52 and 4 star.  

I submitted an appeal form on the day and am still locked out of my account.  I hope this can be resolved quickly.  I have already missed 2 days of in game events.  This has actually been very upsetting.

Thank you for looking into this.
