Pay my money now I've got other commitments

I've arranged to change my debit order date for the bank loan & credit card well in advance, but to my dismay the bank did multiple debits for the same account. They've doubled their repayment which was not the agreement. My account is not on arrears I payed for July and August but why the double debits. They also have a tendency of pestering clients with multiple sms's and phone calls, for fabricated accounts arreas. Is this their way of recovering their profits from the COVID 19 blow? But now their deficit doesn't concern us. The very same bank refused to give us the COVID holiday repayment. Am disgusted by their appauling service and being inconsiderate to clients. The audacity of cleaning my account while I don't owe them and the inconvenience they caused, other debits will not go through as they have cleaned my account. They took almost R16000 plus the insufficient funds charges. The consultant told me to wait 48 hours to assist me as the manager is not in. This is absolute nonsense they run a bank like a tuckshop. I want my money reversed immediately and stop your irritating calls. Am going to report you to the ombudsman for harassment as some of your call centre consultants are very rude and inhumane.
