Come home from deployment to banned account?

Hi I am in the Army and just came back from a 5 month deployment only to see that my account has been permanently banned, I have read the email sent and it says if I remember correctly for third party software during a time period that I was gone. I have spent money and time on this account and would like proof because I do not see how I could get banned while not even in America or having access to internet for that matter. At your request I am able to provide my deployment orders as proof I was indeed gone and my xfinity bill with mac address with proof that I didn't even have internet service for months please respond it would be greatly appreciated. As far as im concerned either my account was hacked or I got flagged because I dual boot kali linux on this desktop also and have pin testing software as that is my job if that is the case, could there be some directory or link explaining what programs and actions may get people flagged although I figured they are two different OS systems and should not correlate directly.
