Bad service

ON 31/09/2020 I phoned Standard bank to get settlement amounts on two of my accounts and got the amounts and paid them the same day. On 31/09/2020 I phoned again to close the accounts and was told to phone back on 02/09/2020 because the payment is not reflecting yet. Wich I did and was told that they have a high call volume and will phone me back the same day to close the account. Today is 03/09/2020 14:05 and still no one from Standard bank phoned me back to close the accounts.
