Air france compensation claim process time

My flight back in August was cancelled and rebooked. I submitted claim and they approved it. On early September, I even got an email from Air France with the payment confirmation and that the payment was processed. However, it never hit my bank (Bank of America) and now it's been over 3 weeks, so I contacted CS multiple times but they said they don't have access to tracking bank payment and haven't heard back from the finance department yet.

How long does it usually take for the compensation to be actually wired to the bank? Does anyone know how to approach in this situation?
