********* business practice

My vehicle was sold on 18 March 2022 and the dealer paid the settlement amount directly into my Wesbank account. The settlement shows on both my Wesbank statement and transaction history. Despite this, Wesbank debited my account with a monthly installment on 25 March 2022. I’ve sent numerous emails with all the necessary proof and documents, but Wesbank has still not refunded the debit order which was deducted in error. This constitutes as ********* business practice and ***** as I am not liable to pay for something that I don’t own anymore and the account was settlement with the settlement amount provided to the dealer by Wesbank. Could someone please urgently assist with refunding the debit order processed on 25 March 2022 and also assist with closing my account as it has been settled? The service I’ve received from Wesbank has been shocking. I’ve been a loyal customer for almost 10 years and am very disappointed by how customers are treated
