After disabled of an gmail account how to request for getting return

I don't know what happened to my google account. But I am thinking that I have broken any Terms of service or violating any polices. But by account carries very important emails, docs and few of products of google, please review my email address. If I truly violate any rules, please inform me how can solve it and return back my google account. Or if there is no options to return my account please give me an opportunities to access for 3 days that I can restore my important data what I must need. Please consider my request.

Thank you
