Nedbank doesn't want to pay

I am utterly disgusted by the service and the handling of Nedbank (Greenmarket Square) From the managers Nolitha & Fatima who lie and make empty promises. Then there is Bridgette who seems to not know what she's doing t all. We are a Savings Club that invests with Nedbank it's been years now. We put in notice on the 28/11/2018 hoping to get our money 48hrs later. The amount of time went by no money. We enquired we were told that there is a back log we understood. 06/12/2018 still no money and we are being fed lies and being sent from pillar to post. The signatories from our Savings Club have been at the bank from yesterday trying to get answers but we are being fed lies and promises that it will come through/reflect. And have now being threatened to be escorted off the premises by police/task team because we want our money how? Is this how you treat your clients when you have our money. Nedbank is not doing us a favour that is our money we are entitled to it and we want it. I don't know how many times we've complained and nothing gets done. If this is how you treat clients then go ahead but i will not be bul**** and abused by you and your staff. We want our money and then we'll gladly take our business elsewhere
