Unavailable deposit funds

Its been more than 12hours since I did an ATM cash deposit . The money has not been cleared. I did the deposit at 20:00 hours yesterday and again another deposit this morning at 06:50, the funds reflected as available but my account still not credited. I only discovered this after having to do a very important paymen, you can only imagine the embarrassment I went through when my payment was declined. Went to the branch only to be told that funds deposited on ATMs after banking hours reflects after 24 - 48 hours. But I found this very disturbing because there is no notice anywhere that warned clients about this even their advert on ATM Cash deposits is MISLEADING "It has never been quicker or easier" NEDBANK ATM DEPOSITS ARE NOT THAT EASY AND QUICK! I learnt a huge lesson and I will never do it again. This is the ONLY bank that holds an ATM cash deposit for 48 hours pending authorisation in South Africa. Never do ATM cash deposits after banking hours especially if you have immediate commitments!!!
