You actually didn't send a modmail asking for clarification, but that would be the avenue you would need to go through to get that clarification.... If you had been banned.
You were never banned. I looked through modmail, and the mod log, and you were never banned or unbanned. Not sure why you feel the need to stir up controversy lol

quick edit because OP responded further down:
OH Okay, so you're using alternate accounts. Not a great look, considering Reddit's sitewide ToS, just so you know.
$1Comments in question were:
> Just quite if you feel that way. I worked at Subway for 4 years and it was much worse.
and
> I can see why they fired you😁
Then the modmail you sent to ask why you were banned:
> Why? Can you provide any information on what I did that is so egregious? Is it because I didn’t bash on Starbucks? Are all of you disgruntled employees who are just here to complain?
This would be why you received a permaban; normally if people "appeal"/ask about the ban and aren't accusatory or hostile, the ban is reduced (i.e. made temp instead). You sent 3 messages, the first two were 10 minutes apart and the third being a couple hours later. Mind you, your responses were 3 hours after the ban. This post was made roughly an hour after the second message.
My response would normally be, "what justified that response to you?" in regards to telling someone that they deserved to be fired. That doesn't fly in the main subreddit and it wouldn't fly here, either. Especially with making a whole post in the sister subreddit to stir up more controversy.
But now my question is why would you use two accounts on both subreddits, one 4 months old and one about 1 month old. Starts to lead to questions like how many accounts exactly do you have, have you been banned before for similar behaviour, etc.
