been told wrong information from bank

I previously been to nedbank to close my garranteed dream maker, the consultant helps me out, I give him details and all documents and he says my dream maker account is closed and the money will be paid into my bank account. I call them few days later afte that, they tell me it can't be paid to me. And the call center lady has no help whatsover, all she can say is she can't do nothing, I want my money that is all, and I don't want to hear no, I need it asap, if not I will voice my issue to the public, because this is not the 1st time I'm having a problem with service, I ve previously complained with no avail, I need my cash asap.
