Standard Bank -Do Better!

Standard Bank you are suppose to help and protect your customers monies. Multiple debit orders(unauthorised debit orders) went off from my friend’s account. In which he quickly went to the Mall of Tembisa branch to inquire and get them reversed.He was told to come the following day, meanwhile his balance is now on a minus and he’s expecting-real and authorised debit orders that will bounce because of this. Why must he come the following day? How do you allow a foreign company to debit your client without authorisation?
