Closing an African Bank Account

So, my issue is as follows. I did not manage to renew my work permit. African Bank they blocked my account because I don’t have the new work permit. I then decided to close the account since I no longer meet the bank requirements. To my surprise I was told that they require me to have the new permit for them to be able to close the account. I don’t have the permit they require, and I won’t be able to get one, so what happens then? The account will just continue accruing charges until its negative then I end up owing them and then I get blacklisted and so forth so forth…. I spoke to a lady called Juliet from African Bank complaints who informed me they can’t close the account because of FICA. I then called FICA call centre, and they told me that there is no restriction from FICA that barres an individual from closing their account if they don’t have a work permit. African Bank can you please just close my account.
