Would you mind giving me some advice?

I have a question about funds after sales, would you mind giving me some advice?

I just sold my items in Amazon in last December, I fulfilled this deal, after this deal was done perfectly, something happened.

My money is possessed by Amazon, I set up my bank info in my Amazon US account to initiate a fund transfer, due to type of my bank account I provided,this transaction failed,then my seller account had been closed by myself accidentally,I cannot log into it or set up my bank info any more.

So I cannot initiate another fund transfer, Amazon refuses to help me.,they ask me to register again,but they don’t approve my application after I summited as same as the documents provided in the last time.

How can I get my funds?
