Bad service

On the 26th October I withdrew money at a Nedbank ATM where the money was processed on my account but money was not released by the ATM. I called the bank several times for this query and I was told that a case has been logged and should take up to 4 working days . 5 days later I received an SMS stating that the case was resolved and the money would be deposited back into my account it's been 12 days now and after calling multiple times and explaining my story each time to a different customer service agent and being told that I would be contacted back which never happened, on last week Wednesday 03/11/2021 I was told the money was deposited back into my account and should be reflecting latest by the Friday and today 08/11/2021 I have still never received my R2500 that I simply just wanted to withdraw as per normal. Nedbank's consultants are useless and I don't understand how is it customer service when there is no service rendered to me it's been a battle fighting and spending hours on a waiting line trying to get hold of someone to assist me at this point I don't know what to do I'm just fed up of fighting for service and wish even a simple situation like this could be handled In a more professional and helpful manner.
