Money gone and no assistance from Nedbank Namibia

I have a cheque account for many years with Nedbank Namibia. I have not been actively using it for some time now, but deposited money now and then in it. I wanted to withdrew the money just to find out I cant. I contacted Nedbank Namibia, one week ago, and they said my name and account is not on their system!!! They wanted my card number. My card is the old one with no number on it! I ask them if I should scan it and send it to them, to which I got no reply.<br> <br> I contacted them again to assist me, as I have money in the account and the only answer I had gotten from them, is that its under investigation, an email from Selma Alupe stated. <br> <br> Now what? Where is my money?? They are now quiet!! All i want is my money and to close that account! What have they done with my money??
