Nedbank's poor Service

Have been a Nedbank Client since 1981. The account which was used for my catering business, together with overdraft facility was closed 2016 when I moved to WC. Opened Nedbank acc again on my return in 2018 and restarted my business. On requesting OD facility this morning, I was told I had to be in someone else's employment. Norisa at *** refused my request. This while Nedbank is sitting with evidence of what goes thru my account. Does Nedbank want to imply that they do not have 1 entrepreneur on their books with an OD facility? If this is the case, I find it abhorable and hard to believe. This is not how you look after your longstanding clients. They were however offering me a credit card! Laughable.
