What's the chance of getting a terminated account back?

I've been playing roblox on the same account since 2017, and I've just been terminated for a voice chat conversation I had on rate my avatar. Now, I can recall swearing a couple of times, but that usually only lands me a 3 day ban or a week at most. I didn't say anything very problematic like slurs or whatever, so I'm wondering what exactly could've done it and what the chances of getting my account back are.
