FNB business account

I have a personal ABSA account and transferred some money to my FNB business account. I did the online EFT on Sunday (4 days ago) and the money is still not in the account. I have been to both banks and both are just pointing fingers at each other. I have reviewed all payment details and everything is correct. I am clients of both banks but none seem willing to sort anything out. I cannot run my business if this money is not in my account and subsequently I am losing valuable business.
