Continued dereliction of duty by Nedbank

We as a company have a few branches. Our branches bank with Nedbank. For the past few months when our staff go to Nedbanlk Branches, specific Protea Gardens Soweto, they get told that they can't assist them with change. This issue have come up more that once, thus me contacting their Client Complaints who reckon we should be phoning ahead in order for them to have change. Firstly your branch was aware that all businesses would require change from the 25th of the month secondly your branch manager have been made aware by the store sine the 25th June 2018 that they requires change and still till today 6/7/18 they can't provide them with change. This is continued in subordination action from management side that carries the approval from Nedbank Head Office. It is shocking that in this day and age where competition is fierce between banking institutions that a Brand like Nedbank allows this continued dereliction of a branch manger to continue!!!! Nedbank if you can't make sure your employee's do their jobs then maybe YOU NEDBANK should get out of the banking industry. As for your complaints department best save yourselves some money and close it, they are useless!!!!
