Second Complaint, same issue!!!

Had a reversal complaint two months ago, it was handled by Marilyn Petersen from Nedbank promptly and professionally. My frustration is back with Nedbank reversals being credited and now AGAIN being deducted from the same complaint with erratic amounts and references that makes NO sense. I just had a 55min call to Nedbank, three consultants later and a dispute form sent that will cost ME R150 should I be at fault, a real mess from a public enterprise that's supposed to keep MY money safe and needs to heart?????? I am now closing all ties with Nedbank, this is just enough of how companies have NO clue and transfer responsibility to THEIR customers and the public at large!!!
