I am so furious with Capitec Bank

I am very very very disappointed with Capitec Bank. I do offer language services to a number of clients including the SADC Secretariat. There is this payment which has been wired since November the 15th 2019...guess what, NOTHING in my capitec account to date. I have been told that the funds may have been returned to the sender (SADC) because of an error in the payment process (illogical). I have lodged a formal complaint hoping that something normal will transpire from it. I can not believe that such a transaction takes more than two weeks to clear...unbelievable. I am planning to leave the bank for good as this has caused serious damage in my family. Capitec seems not to be that good with receiving international payments.
