Unhappy client

What I need, immediately 1. Cancel both existing debit orders of R2 000 and R5 000 to the ContractSave account, effective before the next run date (21 July 2025). 2. Set up a single debit order of R1 000, to be deducted on the 21st of every month. 3. Written confirmation (e-mail or SMS) within three working days that the above actions have been completed. 4. An explanation of how Standard Bank will prevent similar service failures in future—both for myself and other clients.
