Transaction taking forever to reflect on other accounts

I sent money on Sunday to two different banks and today it's Thursday the money has not reflected I tried to follow up and was told it will reflect the follow day it's nwk midday and the money has not even related. It suppose to take to working day to reflect. Now it seems like it's 3 or more working days just for a simple transaction which other banks it doesn't take this one. I am very disappointed in FNB
