Poor service

I’ve got a African bank account for quite a few years now. I went to the Silverton branch to get statements older than a year as you can only get one years statements on the app. The person who was handling the matter just told me that she cannot give me statements and she phoned their call centre and this person also told me the same. She told me that I must go to my email and look there as they send it monthly as well. I opened the email and it redirects you to African banks site where once again you can only see up to a year ago, not further. It seems to me that I should change banks.
