Horrifying systems!

I am utterly horrified with the updates and systems links that Standard bank uses. How does one make a purchase at a store, get an sms showing the balance reduced by that amount and a few days later have their balance reduced by the same amount again!!!!!<br> <br> I called in to query why my account was in a negative balance only to be told i was double debited, and the amount was reversed. i made a transaction on the account and called back to check the status, and NEGATIVE... i'm told the transaction went through in error and all transactions I've done were allowed even with no funds. <br> <br> How do i get an sms saying a positive balance, and 10 minutes later negative!! How does my internet banking showing a positive balance and the agent tells me i have a negative balance!!!<br> <br> I am disgusted in the manner my account is being handled, especially when i rely on sms and internet notifications. <br> <br> This is the worst service i have ever received, how does one trust such actions when their means of living are concerned!!!<br> <br>
