Nedbank disappointment

I am utterly disgusted by the poor customer service I received from Nedbank (contact centre). I spoke to a Cebo Gamede and I asked if Nedbank can help me accept a debit check mandate since I could not access my banking app, she said she does not know how to do that and she offered to put me back on the queue to get an agent that knows how to assist and I refused that and I asked to speak to a teamleader she then said her teamleader was busy on a call, I said I would wait, she then said I could not wait on "her line" as she was busy working, she had a very sarcastic tone, when the team leader came she was of no help displayed no leadership skills she was rather confrontational (Phindi Mweli) is her name. I would like Ettienenne Neethling to listen to this call advise if this is Nedbank's standards and action Called from number : *** Thanks Ryan
