International payments through 3rd party apps.

I live overseas. I have used my Capitec account for years for payments through 3rd parties, such as Paypal, Wise etc. All of a sudden, my payments are not going through. Wise app said that Capitec is not authorising my payments. I phoned Capitec, then was told to phone the FX account line. The agent then told me unfortunately I have to open a different account to make these payments. I asked him why, where's the notification for this, and he just said "I don't know what to tell you mam, we were advised to tell you this is what you need to do". So after years, I now have to change accounts, or open a bank account with another bank, so that I can use my own money, how I want.... This is a HUGE problem because I am studying, and need to make regular payments to my university which is not in SA. After many emails, I still have no answer or no clue what to do.
