Standard Bank App is useless weekends - payments are not processed

I made a payment from Standard bank app into an ABSA account on Sat 26 Feb, today is Monday 28 Feb the money is still not reflecting on the ABASA account. I phone the customer care only to be told business days is Mon to Fri so it's like I first made the payment today and would take 2-3 business day to clear.

So standard bank app is for weekdays as during weekends it is useless as transaction is disregarded until the next business day which is Monday.
