Extremely slow delay in fee credits requested for erroneous charges on an account

I am escalating an issue relating to fees that were erroneously charged to an account despite a migration of the account status from end of July. I had submitted a request for all fees charged from July erroneously charged for a Private Bank account.

It's been 3 weeks since the issue was raised and esclated and there has been no update from the finance department on the reversal of charges to date. It's now got to the point where your risk team reached out about an overdrawn amount on the account.
