Beware: Sen_The_Folf

This is my first time writing something like this so I apologize if it's a little all over the place.

For winter I have been taking holiday icon commissions, mostly to fund my medical bill expenses and my medications. Nothing was suspicious at first, everything seemed fine.

I normally take my commissions through Telegram and sell there, so this wasn't odd in the slightest. They proceed to then ask me if they could get their character drawn, to which I agree. 

About three days later, I end up finishing their holiday icon and send them the file. 

(You can see that they are still using the art as their profile picture on Telegram as well)

Everything was fine, though today at around 5pm I got an email from PayPal saying that a case was opened.

I was not expecting this at all, as I had finished their icon 2 weeks prior and we had no issues. I have never had this happen before, but after talking with someone I'm close to, I figured out what to do. I ended up putting my own info into the case, stating that they had paid for the piece on the 5th of this month, and then I finished on the 8th of this month. I had included a screenshot of our conversation to PayPal.

They put this under 'unauthorized purchase' even though we had clearly discussed this over Telegram and they confirmed that they did indeed send the money over to my PayPal. I'm not sure what to do, or how long this will take (it said it could take up to 30 days, but I just don't know if there's a general time before that where they usually solve this?)

Any advice/help would mean a lot to me, as this has never happened to me before and I'm not 100% sure what to do at this point. Do I just wait it out and hope?

Thank you for reading this!!
