I recieved a Permanent Ban but can't submit a case review

Hi Xbox community, about a month ago I received a permanent ban for my Gamerpic (a normal picture of me and my friends). I was very surprised when I logged into Xbox enforcement history and saw that the ban was permanent. I was at work at the time so I did not take the time to fill out the case review, however, I know there was an option to do so. Today, I logged back onto Xbox's enforcement page to write out my case review but It did not give me that option. A permanent ban for a picture of my friends and I seems very extreme, especially with no prior ban history. Any assistance the community could give me would be greatly appreciated.

:)
