Nedbank freezing account with out notification

Good day, I have been banking with nedbank for sometime now but this past week I have been disappointed by their service. I received a payment and my account was frozen. I have tried to contact them but all in vain. I have no way to pay my clients and my business is inconvenienced. I hope I can be helped as soon as possible.

I was told that someone complained about not receiving the goods they paid for. I used a courier company which delayed the delivery but even after the client received his goods, nedbank has failed to open my account.

I called the bank but they put me on hold until they either drop or my airtime runs out.

My name is Thabang Richmond Maluleka.

Account number : *** Hope I will be helped as I am out of options
