My Gmail account was disabled now i want it enable

Hello,
My Google email account disabled and I have no idea what to do and I don't feel like I violated the terms of service. I have only been using my email, for my bank account and social media groups and email lately. I've applied for a lot of jobs and I need my email address for those employeers that wish to contact me through email which is how some already have. I've already tried all the ways stated on this forum already. None of them work. I can't use the forum because u need to log in to ask anything. My account is removed by moderator@mail.com So I also need this email for my education (Masters Programme). All the teachers and the school management of University of Ibadan, Nigeria use the emails to send the students important information for their classes.
