limited online processing capabilities

I paid my maintenance service provider via internet banking at standard bank to complete some work, but he did not receive the money although he also banks with Standard bank. I have spoken to Mamelo Rakeepile as well as escalated to Jonathan Olifant who stated the internal bank payments take 24 hours while other bank payments take up to 3 days. they have acknowledged that they do not have the capabilities of immediate payments for internal accounts like other banks and still need to get there. when questioned why, they have asked me to read the fine print. I am highly irate as my work is standing because Standard bank does not have up to date technology to service their clients. Talk about stone age banking.
