Not informing clients about unavailability of immediate payment system

Standard Bank is so ridiculous. I attempted to make an urgent payment to my Capitec bank account using the immediate payment system, however no indication that the immediate payment system is unavailable was given prior and now it will be done through the normal process which takes 2 business days. I only found out when I called them that the immediate payment is unavailable, and I am left stranded because they didn't notify us as clients that the system is unavailable because I wouldn't have made the payment. They can't reverse it also, how ridiculous is this nonsense, leaving me stranded because I needed those funds now!!!
