Banks mistake and no refund

My husband went in to capitec 2 days ago to have his new phone number assigned ti his caputec savings account. The bank did not inform him that the number was assigned to another account already. (Recycled number by vodacom) Today I transfer the last of our money for the month into his account via his cell number. But it doesn't reflect when we try to draw it at the atm. Run straight to bathe branch and ask them to reverse it immediately. They say if it's not his bank account he can't. So I say well reverse my paymemt it was a mistake. They can't do that either.

No they want to get hold of the person linked to the number but she doesn't have the number anymore. So.in that case we must wait or be advised we wont get it back. We had no petrol to leave and had to walk home. We now sit with no cash at all. All the time no one seems worried or goes the extra mile to help.banks just don't care.
