International payment release and online banking app

Long story very short: for heaven's sake how long does it take for money to be available in Absa account as it's already released from UK bank. I mean like really! AND I'm not done yet! Why is Internet FOREVER an issue during the night to log on whereas it suppose to be 24/7. One would never be able to log in during the night but miraculously within seconds during the day. Age come on man.
