Inconvenience and poorest of the poor service

I deposited a cash at an ATM on Monday 28th, a technical error reflected on the screen, I did not receive proof of payment, money was not allocated to the recepient's account. It was a night mare of my life. That was not enough! On logging a customer complaint, the consultant captured incorrect amount (less by a thousand R1000). Therefore a refund made this morning only, was less by R1000. Further inconvenience, I have made numerous calls with no resolution, today I spoke to nine consultants, I have been pushed from pillar to post, all of them making empty promises, not returning calls. Their team leaders are too important to take phone calls. One of the consultant was so stubborn, she refused to escalate, instead argued with me and frustrating me further. I have never come across such poor service ever. Never been so inconvenience. I am considering closing my Nedbank account.
