Standard Bank cannot be trusted

I tried to withdraw money from an Standard Bank ATM. I received a sms that the account was successful, but a few minutes later I got a message to retrieve my card. Then I got a statement that the transaction was cancelled. I called Standard Bank when I got home and reported it. I was informed that it will take 24 hours. The next day I called again and was told it will take 7 days. I obtained a ref, but it turns out it belonged to another client. They reported a new ref and I was told it will now take 7 days. 7 days passed and I called again. I was told they will call me in 2 days. 9 Days later I received a sms stating that they were still busy investigating. I called again and received some more promises.
