Business disaster

Mercantile was taken over this month by Capitec, I have been receiving a monthly payment (salary) from my Wise account for the last 18 months. This month the payment has been pending for 3 days. AZA finance tries to contact Capitec to confirm payment-they say it's done IT IS NOT!!! and so the circle continues. Capitec takes a day to reply and AZA just waits around for feedback, no one does anything to clear my payment that has been seamlessly transferred for 18 months before you came into the picture. No one at Capitec branches knows anything about international transfers and you have no team that can be contacted for support. SOMEONE HELP ME!!!!!!!!!!
