Nedbank ATM deposit nightmare

On the 6 Dec I made an ATM deposit of R7000. I received a receipt as confirmation of the deposit. I misplaced the slip and did not think of it until I got home and was surprised that I didn't get an sms confirmation of the deposit I made. I then called the contact centre to lodge my complaint. They said they escalated it to the ATM department. I also lodged an e.ail complaint to have the issue resolved. Received a call from a manager on the 7 December advising he will escalate the matter and sent his contact details via email. He said it would take a few days as I didn't have slip . It's going to 2 weeks and no closer to a resolution. I am now in this position due to their system issues and am appaled at this service delivery. I have been depositing via ATM for years and you take it for granted that it will deposit correctly each time .
