Nedbank bad service

Bad experience from Nedbank. On the 15th of may I withdrew some funds from my Nedbank account and the ATM did not dispense the money .I received the card and receipt. I received an in contact sms showing that the funds where withdrawn.I immediately went inside the branch to report the matter .A case was opened but I had to make follow up each and every day.all I got was false promises from the agents including the manager who was handling the case.I am just shocked with the horrible service I received. I never got any help no refund or what do Ever from this bank.
