WITHOLDING MY SALARY WITH NO CUSTOMER SERVICE WHATSOEVER.

I've been trying to get in touch with Bidvest Bank's Mandate department SINCE LAST WEEK as they're experiencing an error on their side which is preventing me from receiving my salary from overseas. Their phone lines don't work, they don't bother answering their emails, and they've basically LEFT ME STRANDED WITHOUT AN INCOME even though I've done nothing wrong on my end. Nobody else at Bidvest Bank can help me or even answer any questions I have, and I'm completely MORTIFIED WITH THE EXPERIENCE I'M HAVING. It feels like nobody cares because it's not their salary being witheld from them. And to be honest, it's been YEARS since I've experienced such horrible customer service, especially for a service that's SO crucial for the customers. CAN SOMEONE FROM BIDVEST'S MANDATE DEPARTMENT PLEASE HELP ME???
