Ask HN: Amazon account is suspended and I lost all tax documents. What to do?

My Amazon seller account got deactivated 5 months ago with no specified reason. Due to being busy with school and some health issues, I stopped selling this year and did not see this message. My account is now deleted, with "no way to access any information." All my tax documents, sale records and revenue info is gone. My fund is frozen with an appeal method that is ghosted (idk how much balance i have). Customer support told me to seek legal advise when doing tax return and wait for refund appeal

What can I do? I paid seller subscription which includes tax handling. Do I have a legal case to require them to send me my account data? Does Amazon actually delete account data in just 5 months?

edit: im willing to spend good effort and money to fight this corporate whim
