Service non-existent - No communication re renewal of SARB 2025

My husband’s business has received a monthly international payment through WISE, but was informed that he must submit the 2025 SARB Mandate before the funds will be released. Mandate was completed & supporting documents were been submitted on Monday, 6 January 2025. There had been no feedback. We have e-mailed the relevant department to follow-up, but no response. We have contact the number to follow-up and the automated response is that they have high volumes due to the 2025 SARB Mandate, then the phone just cuts off. I have also escalated the matter through their website. No feedback whatsoever, not even an automated response with turnaround times. This is absolutely shocking considering that numerous clients who receive Wise international payments have to work through Bidvest Bank.
