Unacceptable client service from Nedbank

My brother who lives in Canada has a blocked rand account with Nedbank. Because they did not activate his account on time (as he requested well in advance) he had to borrow money from me. On his return to Canada he instructed Nedbank on 22 February 2018 to refund me the money that he borrowed from me. This request was followed up on numerous occasions with the promise that it would be done before the end of the day. A transaction like that would only take minutes to complete and not hours. As the money has not been transferred to date, I also send a complaint to Nedbank customer service (Ref # ********** 5) on 16 March. It was stated that this matter would receive urgent attention. To date except for the reference number, there was no other response an the transaction has not been done. It looks like Nedbank is becoming like one of the government institutions where you are send from post to pillar with empty promises. Maybe it is time to vote with our feet and close the accounts with Nedbank.
