Call Centre Worse Customer Services EVER!!!

I phoned Nedbank 6th times this morning for a mistake on their side. I have been transferred from the 1 dept to another for a duplicate debit order. When I ask the call centre agent (Nomthanpazo) if I can go and reverse the wrongly debit order she said no I have to speak to the dept that Is doing it. She transferred me. I spoke to Esme who said their cant do it i need to speak to another dept, She transferred me. I spoke to Philea he could not help me and cut the phone call. I phoned back and was transferred again by the switchboard, I Spoke to Walsh, he cut the phone. I phoned back i spoke to surhaim, he eventually cut to phone again. First the debit orders is loaded incorrectly according to arrangements. Now that i need to get my payment back the phone has been dropped for 5 TIMES!!!!!
