No care for clients

Penalty charges for trying to take funds earlier than agreed after I called them to not do this. I received a message earlier in the month saying they would attempt to take money on Friday 24 October. I immediately called them and ask them not to do this as I only receive my salary on the 25th. The agent I spoke to said there would be no charges on my account and I explained if there is no funds I get charged for the attempt. I signed a DebiCheck mandate agreeing that they may only take the funds from my account on the 25th. This is costing me penalty charges of R150. I want a refund of this immediately and I want you to stop deducting from my account earlier than agreed.
