Issue with a wire transfer

I wire money from Chase Bank to Central African Republic. Chase Bank debit my account and never deposit the money to the recipient Bank. This issue is pending since May 11 2019.
Chase is not answering my emails, refuse to send any communication per email. Gave 3 different reasons why the deposit was not done:

1. The money was more or less "stuck" at intermediary Bank, which was not able to perform the deposit at the beneficiary Bank. Money will be send back to Chase Bank asap, and Chase will deposit on my account.
2. Money is pending to be deposit at the beneficiary bank, but Chase is still waiting for an answer to their swift message, they send to the beneficiary Bank.
3. Last version, Money is back from Intermediary Bank to Chase Bank, but Chase will not deposit the money on my account, until they get confirmation form Beneficiary of a VOID Transaction. I need to get in touch with Beneficiary Bank to have them send confirmation to Chase Bank. Either way my money will be stuck forever at Chase Bank

Please let me know what kind of lawyer I need to contact.
Thank you

 

I visited the Branch several times and speak with human beings several times. And receiving several versions of this issue. calling several times and not receiving calls back. the reason why I think that I need an attorney is that I don't even know whether my money is lost or not. I have been patient for 3 weeks.
