Bad service

My husband app**** for a card and after much queries collected his card on 22 August which was the wrong branch anyway. So he used his card and on Monday card blocked. I understand that nedbank was protecting him however he confirmed that it was indeed him that used the card.spoke to Itumleng and she promised that they will call him.No call. Mercia called on the evening of the 25 or 26 and confirmed with him all that needed clarity and assured him that the hold will be removed.Well this was not done and on Saturday he tried to use the card did not go through. Called card ***** again spoke to another gentleman who put him through another person...He held on for 15 minutes...number 1 in queue. Called cut off. Called back spoke to Kanya who promised to get Daisy the manager to call .still waiting. I called again this morning and Kanye answered again and she remembered our call of Saturday.She promised that a manager will call .welk still waiting..really sad situation and bad service
