I recently changed my Standard Bank account and have an issue with a debit order. i wasted all my airtime trying to contact a consultant instead of a computer and even emailed my private banker on more than one occasion requesting a call. Granted she did try and the call appeared as spam. How do I actually speak to a human being to assist with my dilemma or is the only way wasting more of my time going into the branch and waiting for an hour. Very disappointed now that i upgraded my account :-(
