Changed banking details

On the 14th of May2015 we went to old mutual in centurion mall regarding change of banking details Madeleine Dreyer assist us regarding the matter that took her 3 hours to fill in forms then she confirmed that everything is in order and that head office had received it. I called several of times to confirm that everything is in order . At the end of May they made the payment in my closed account at nedbank so I've called again to ask why and i did speak to the Manager Ibrahim and he said he will follow the matter up and end of June the exact same thing happened. On the 25th of June Ibrahim came to my home to give me forms that they forgot to give me and now it is my duty to go to Nedbank to get a form that states my account is closed after nearly 2 months. I am so fed up with this situation . We rely on this money because we are pensionerares. As Ibrahim will confirm that my brother passed away and we needed money regarding the funeral so i had to borrow money from my son in law and i cant pay him back because the money is some where in a nedbank account which is not mine my nedbank account is closed ...Alida Viljoen ***
