https://help.instagram.com/contact/364531043625021 I think that's the right link to contact them. Just be sort of honest about the situation and make it a bit into a sob story, but not too much and they might be generous after a few days to restore it. Sometimes it works. Sometimes it doesn't. If you don't want to go that route I think there was one person on the forum who had a service for unbanning accounts but it'll cost you some money I think.
In my honest opinion, you should just move on. It's only 2K followers. That's nothing. You can make that back in 2-3 days and if you truly want to make money you should have at least 10 accounts as to prevent worries about bans such as this. I do hope you realize from now on it's silly to add any types of links to your ig accounts.. and any other noobies out there that might be reading this. I see a lot of people getting banned for this but they just don't want to stop.. so hey, less competition I guess for the long-term people.
