Very disappointing

Having used my ABSA credit card at an FNB ATM where by my account was debited although the transaction never happened du to a technical error. I called the number provided on the sms from ABSA *** to which there is no option for the transaction that took place. I was eventually told I need to contact FNB as it was there ATM. I called FNB where the call was handled very professionally by a private banker call agent but that is where it ended. I was passed on from pillar to post call center agent to call center agent department to department evenly landing up at an abrupt rude person who basically told me he was doing me a favour and would find out who was responsible for the machine and I was to call him. The call was then disconnected. No return call has taken place Nearly 24 hours later I have had no resolution to this problem and without a human to talk too.
