Complain about WesBank deduction

I requested to pay my account on the 15th of December 2022 double because of financial difficulties. There was an agreement that I can double the amount and on the 15th an amount of R11 700.00 was paid and same day R11 400.00 was deducted from my account by WesBank now I am been sent from pillar to post and told that it will take + - seven days to get my money back. In the meantime other debit orders must go through. None of the three WesBank collections department staff members was prepared to assist me until I called WesBank customer care service and I was assisted by a lady call Nomfundo Mehlala whom I applaud and appreciate, because she was eager to help me and she was very patient.Double deduction was made by WesBank.
