Very poor customer care

I had incoming foreign currency into my Business account which needs to ne cleared and deposited. I got the email and responded to all questions to have the money cleared. It has been 4 working days I am waiting for the funds to clear. I sent emails and no one bothers to repond. I have made calls and they keep saying they will try to follow up. Uo until now I am still struggling to get a simple response to understand why it takes 4 days to just clear funds. I need to make payments to my creditors , but ABSA is taking their time, whilst I incur penalties.
