Service, WHAT service, does not exist.

Since I received my IT3B on 24-06-2019 and looking for certain information on it (Interest Earned In That Tax Year) and finding that all Nedbank reflected was “total accumulated interest”, I had a problem. During the early part of July 2019, I went to my local branch in Riversdale, WC. There I went from one person to the next enquiring about the information I needed. Eventually I was sent to the information counter where the lady was not able to assist me. She phoned their call center and was transferred from one person to the next. After speaking to four different staff members she was told the person who could help was not available, so arrangements were made that they contact me. Never received a call. On 12 July 2019 I sent an email to *** giving them all the information and requesting assistance. On the 14 July 2019 I sent the same email asking for a response. No response. After that I visited the local branch manager Mrs. A Dorfling and a few emails were sent between us with delays from both sides due to computer email problems. (Between 15 July and 31 July.) On 1 Aug 2019 I received copy of email sent by Nedbank HO to Mrs. Dorfling in which they stated that they do not supply the information I needed. I had another appointment with Mrs. Dorfling (around 22 Aug 2019) and emails were sent between her and the HO, but with the same result that I was not given information I required. On 23 Sept 2019 I sent an email to Bianca Thompson acknowledging that the information which I required was on monthly statement but that there was a further problem in that Nedbank were not sending me or my wife all our statements. After all the time spent to try and get the information all she advised is that I should call their call center. (27 sept 2019) On 4 Oct 2019 I sent her above reply and asked that it be escalated to her boss. (Poor service) I never received a reply from anybody. On 8 Oct 2019 I sent the above email to Mrs. Dorfling. On 29 Oct 2019 I again sent an email to Mrs. Dorfling advising that I had still received no assistance. On 1 Nov 2019 Mrs. Dorfling sent me a copy of email she sent to HO. 14 Nov 2019 email to Mrs. Dorfling advising no word from anybody and asking what kind of business is Nedbank.
