Call Centre Non Responsive

I am horrified by Standard Bank's service over the last month or two. I have phone customer service three separate times and each time wait on hold for 15 min + before the call drops or I hang up. The automated message about COVID19 is so outdated, I cannot believe that you would still be operating on limited staff after almost 2 years of living with a pandemic. I have requested a call back, but don't receive contact. I urgently need to be contacted in order to resolve an issue on my banking app.
