Insufficient Support from Nedbank Help-desk

I have been a loyal customer of Nedbank since 1993. Round about the same time I app**** for an overdraft on my cheque account and subsequently used a policy sessioned fir this purpose. Since October 2020 I have been battling to get the session cancelled via Nedbank call-desk but with no luck. I have followed up the request with numerous e-mails but Nedbank has dismally failed to provide any feedback. I have always recommeded Nedbank to all my friends and family. Question is will I still recommend Nedbank? With their utter neglect to provide any feedback for a period of almost a year, I will definitely be very weary to recommend Nedbank to anybody!
