Bad service

I have to say just how disappointed i am with Nedbank Argyle Road Durban. I sometimes wonder if the staff there wants to help you or if they just dont know what thery are doing. I went to this branch on the 23/01/2016 to cancel a stop order that i had, only to b told when i get there that there is no stop order on system. I repeatedly requested that the consulted double check because irrespective of whether money was not available last month for the stop order to go through, i need the stop order cancelled as the account that the money was going into has been changed and therefore i need to update the banking details. I was assured that there is no stop order and if there are problems i should contact *** for any reversals i need to do. After checking my statement and realising the stop order went through,i then called the call centre yesterday, and was told they cant reverse a stop order i need to query with the branch. Now can someone tell me what one does in a situation where you just get tossed around by everyone at nedbank? I want that money from that stop order put back into my account. its not my problem that you hire people that cant read your system. SORT IT OUT!!!!
