POOR SERVICE DELIVERY

I withdrew money from my account at an ATM on the 14th of March 2016. The money was debited from my account (an amount of R1000) however the ATM did not dispense the cash. I have phoned FNB constantly over the last month and have still not received credit for the money that was debited from my account. Each time they come with a new excuse and claim the problem will be rectified and yet here i write this complaint. This is shocking service and not to be expected from a bank that claims to be so customer centric.
