No response from Standard Bank

So, I'm glad I left them in 2018. So, I still have a bond with them and when trying to contact them to give 90 day notice: 1. Their contact email on the site does not work; 2. You call them and wait indefinitely without anyone answering; 3. You try their general email which works but get no response after so many days.

I don't know what to do - I may have to just accept paying penalties due to their incompetence. Maybe I should consult my lawyers.
