Hi guys, i got banned yesterday

. OK i played incursion 9 and i must have high deff and high offensive after the 5th level.. I played the whole 25 levels and my deff was like 15 on special 3 changed to 100 and offensive was like 15.
1 Day after that i logged nornally in, Set deff On 4 and attack on 2 and played alliance wars. After finishing, i Closed the game. several hours later, i started the game from another Phone, without mod. than i saw that i get banned.. i thought i can ask the Support Whats going on, maybe because i changed the Phone. they knew i Was cheating... 7 days ban..
I guess i went too far, is it maybe because of incursion?? Or alliance war?? I mean dmg on 2 and deff on 4 is Not so obvious.. I dont play Battle grounds..
