got scammed through PA, what are my options?

Long story short, I bought a fresh lvl 30 smurf league account that was perm banned days after I received it because the seller botted it to level it up.
The PA tos clearly states that this is not allowed.
I've tried contacting the seller but offcourse he ignores me. This was a guy with over 6000 positive feedback.

I've contacted PA live support and told them my situation, I made a ticket like they told me to. However it's been more than a month now. Everytime the live support gives me the standard "we're working on it" bs, and the ticket has yet to be updated.

Paid trough neteller.
The money was deposited trough online banking to neteller.

Any suggestions on what I could do?
All I want is either a new account that isn't instabanned or my money back.
