Unacceptable Service form Wesbank and Call Centre

Requested a settlement in May 2021. Settled car. Debit order still goig off with costs and interest. When requesting written confirmation of my account and updated statement reflecting the return costs and payments, I am advised it cannot be done. Shocking from a bank of this calibre. When asking to speak to a Supervisor, she is seemingly too afraid to address her client and refers the query back to call centre.
