No immediate clearance in this era!

I opened a Standard Bank Account in December. I tried making a payment now and to clear it immediately as the person needs the money today. So I noticed no immediate clear option. When i called to enquire I was told they do not have that option at all. In this day and age it makes no sense. I also had an EFT from a Standard Bank account to my own Standard Bank Account and it took more than 24 hours to clear. Why is standard bank so sluggish and behind as all other major banks have immediate clearance options when making an EFT as well as from same bank. I think I made a very wrong decision when I switched to Standard Bank.
