24 hrs notice account

I opened a 24 hour notice investment account t electronically. I then placed a notice on money for money to be in my account yesterday, money didn't come through. I called the contact Centre yesterday and I was advised that money will be in my accounht today as thge notice was done at 22:00, it's now day 2 anhd I still done gave money in my account. I have a one year old daughter who is very sick and I don't even have money to take her to the Dr, can't even afford to buy sanitizers and face must to protect my family from Corona virus. What is the purpose of having a 24hours notice account if I won't have my money within 24hours. This is so unfair, I need to stay out of work for 2days taking care of my daughter with no proper medication? I Need my money ASAP I will move all my investments from nedbank after this, il never deal with them.
