Extremely terrible and frustrating customer service from Nedbank

It took for +3 weeks to pay the personal loan that I tried to cancel in week too cause it took too long. Was told there is no need to cancel as there is marriage certificate outstanding, how do you ask for marriage certificate from someone with divorced status, the second cancellation request was sent on the same day by email. Suprisingly on week 4 Nedbank decided to deposit the requested amount into my bank account despite attempts to cancel the application request as it took too long, tat was supposed to be 1 week or 7 days. In attempt to get the money back Nedbank debited my account twice and I have been trying to get the second debit reversed for a week now, the same bank charge for unpaid debit orders for their mistake.

Terrible customer services I have experienced, one day was on call for about 2 hours, was taken round circle and been transferred from one agent to another and been required to explain the same story over and over again, multiple agents trying to log multiple request for one request. 3 times Nedbank agents promised to call back and they haven't as yet as I write this review. Terrible, terrible, terrible and frustrating.
