If you do the Internet equivalent of walking into GitHub without pants and they kick you off, and you gave them money, we can have a conversation about whether they should give you your money back (I guess I probably would). But other than that, what's there to talk about?
Make a new account that isn't traceable to the reputation you lit on fire, or go to any of the other perfectly viable Git hosting sites. You can even run your own.
I get not wanting to tell your boss why your old GitHub account doesn't work anymore, but: you're going to have to have that conversation, probably.
