Shockingly Poor banking service

I lodged a complaint on Monday for a double deduction on Sunday at a restaurant. David told me that I must wait till Thursday to see if the money will be deducted from my account. I called today only to be told David the Capitec is Coert gave me the wrong advise and the they can do nothing now since the money has been paid over to the restaurant. Do we really need such type of banking service. My reference for the call on Monday was ***9. You can listen to the recording. I will test this case of poor banking service with the Ombudsman.
