Misleading Available and Balance account amounts

At multiple occasions I have noticed that after swiping the card for a transaction with the transaction getting completed successfully the Standard Banking app does not registers the entry neither updates the amount in Balance vs Available.

Additionally, the SMS received after a transaction gives one balance amount, the app gives a slightly different amount and the actual amount available is absolutely different !!! That is insane. If the Top Bank (" As claimed") can't do the accounting properly what to do?

And absolutely forget about calling call centre and even service desk at the local branch as all they say is "They didn't know it's like this but they don't know how to even bring this matter to attention within the bank. Sorry".

Please Standard Bank, stop wasting money on expensive adverti*****t, hosting events, etc. and focus on sorting certain processes out including still having to go to OLD website to send a Secure Message... really ??? An old site, New site, multiple Apps ... ???
