I can't make payments - How do international clients get help?

How am I supposed to get help as an international Std Bank customer? If I call your international help line, I wait for 45 minutes for someone to answer. As we start talking, the line goes dead. I don't have funds to keep buying credit for international calls where I pay to listen to music for 45 minutes. You have the option to leave a number to call me back, but all you accept is a local SA number - on your INTERNATIONAL HELP LINE. Of course I don't have a local number!!!! I wrote to your digital helpdesk team on 1 Feb and got a response saying you're working hard as I'm a valued client and you'll get back to me within 24 hours. It's been 17 days and I've had no response. I can't make payments from my Std Bank account. There have been "technical difficulties" for over a month now. SO PLEASE FIX THIS URGENTLY.
