Unauthorised debit

On the 25/11/2017 an amount of R739.06 had gone off my bank account without my authority. Every four years I have this issue with NEDBANK. In 2013 when I spoke to the consultant she told me this matter had been resolved and I no longer need to worry about it. It is now 2017 and this is resurfacing again. This debt has long time prescribed and now you guys are just automatically deducting again. I want my money reversed back into my account or I will be taking this matter further with the banking ombudsman. This is prescribed debt. TPOA36397. For a fine nerve nobody has asked my consent to deduct this amount from my account.
