Non Existant Customer Service

We have been wanting to open an investment account as we are existing Nedbank Customers and have done an online inquiry requesting to be called back on 30.07.2019 in order to be assisted as we require advice. No response. I then called in on 05.08.2019 and asked for assistance to which I was told she would contact the Branch Manager at the East Rand Mall Branch and get them to call us back. No response. I then spoke to Natalie at the Sunward Park branch today 06.08.2019 who promised to call us back to which we have received NO RESPONSE. There are many other willing banks that are far more efficient so we shall be moving the existing as well as future new accounts.
