Fed up with Standard bank service

On the 28/07/2020 I requested the settlement on my personal account. After receiving the settlement I paid the settlement on the same day. Today I went to the bank to close my account. Now Standard bank want R280 more before they can close the account. I received a email stating that my account balance is zero. I have been with Standard bank sins 1991 and al my accounts as well as my family members are banking with Standard bank. I will be closing all my accounts with Standard bank Homeloan Personal account Credit card Business account And the accounts of my family members

I will not pay that the R280
