Arrogant Nebank Employees

I have had a hold put onto my account after I have paid the due amount in full. Thereafter I have contacted Nedbank Customer Care everyday for a week!! Every time I was told that they would call me back but obviously never heard from anyone. I sent through the required documentation while I was on the phone with the consultant. I now am unable to increase the limit on my account. Ruth Davids and Marlin Johnson must have been the most *********** and arrogant employees that I have ever encountered. Today I was again told that I will be contacted back as the admin department does not take calls?????? I cannot wait for the response, after the hold has been removed, I am closing all 3 accounts I have with Nedbank and will be moving over to a new bank who actually wants my business
