Poor service from Nedbank

At my business I have a Nedbank speedpoint machine .The machine banked successfully on the night of the 11/09, however no funds came into our account on the 12/09, I called Nedbank merchant and I was told it should be in by the 13/09, checked again on the 13/09 no funds I called them again got a reference no. and was told it will take 24 to 48 hours to sort out , no problem I agreed to paid , on Wednesday 16/09 as funds still not reflecting , today is the 25/09 , the funds are still not in my bank account and all I am getting from Nedbank is we are escalating , I make 3-4 calls a day to be told wait for tomorrow or the day after we will have a response and when I do call they tell me to wait further , My point is the funds banked successfully on our side , it is reflecting as banked on their side does it take one over 2 weeks to see where the money is , my business like all others have come out of lockdown every cent counts to me , I can’t afford to lose any funds . Nedbank needs to sort their issues but don’t put your clients in a position where they have to beg for their own money . At this time I am thinking of closing my account and looking at another bank cause if Nedbank cannot look after me why should my business be with them , highly disappointed with Nedbank, other than Sia, who made it her responsibility to call me whenever I called thank you , you are one of the reasons I have not moved to another bank , but if my matter is not resolved by 28/09 I will be banking with someone else.
