How do I contact amazon seller support without an account??

It’s pissing me off that I can’t find a way to contact amazon seller without my account. I closed my account by mistake and now there is no way i can contact their customer support. I wanted to sign up as individual seller but unknowingly it singed me as business and charged 39.99 bucks and i thought closing it would refund me. Which they did not. So now I’m left without option om how to contact them.
