4 Calls with confirmation funds will be reversed - 24 hours still nothing!

I have called Capitec 3 times yesterday: 9am, 2pm and 5pm as money needs to be reversed into my account. All 3 times it was confirmed it would be in my account within 30 minutes. It is now 24 hours later. No money reversed, call centre cuts you out completely or call agent can not hear me. I have spent so much money on airtime to resolve a problem that should not have happened in the first place. Please URGENTLY reverse my funds.
