Poor service, lack of communication and no source of agency

Their service is so bad , the agents don't have answers they kept on telling they will sort the issue ,well its been 2 weeks now. On 22 of May i received a notification from Nedbank that my dividends where paid to that account which is not the account I'm using as a result that account was on a negative hence i couldn't get the money. I then called in asking how possible is that ,the agent was also surprised she advised that on the system there is Capitec details. Even my previous divindeds where paid on Capitec. So also told me that they normally pay to the account on System and its Capitec not Nedbank She then told me she escalated the and gave me her Email address her name was Mosele Letsoalo. Since that day i never had from her i had to call in and speak with different agents but all of them never gave me turnaround time.
