Trying to download my tax certificates

Over a 10 day period I have now written 4 emails to various sections in SBSA regarding the fact that I cannot download my tax certificates from the SBSA online banking platform. I copied the messages that I had received:

==== Dear SBSA,

2 issues: 1 I have been trying for more than 24 hours to download the 2021 tax certificate for my MoneyMarket account, only to get this message:

Service Error This service is currently unavailable. Please try again later, while we investigate

2 I had a fixed deposit which terminated towards the end of 2020. This account also requires a tax certificate, but I get the following message:

You do not have any tax certificates available for the selected account. (This is an incorrect statement) ====

In response to my first email I received a response that redirected me. In response to my second, redirected email I received no response. I then send the issue to the business banker in the local branch; no response I then sent the issue to the SBSA Complaints department, no response. I have checked many times if the problem had been rectified, but no.

Other than writing to HelloPeter, I do not know what to do next.
