Sending Customer Away without helping

I GAVE MY FATHER GENERAL POWER OF ATTORNEY ON MY ACCOUNTS AS WELL AS ON MY CHILDREN'S ACCOUNTS AND WHEN HE VISITED ABSA BANK YORK STREET HE WAS SENT AWAY BY LIZ VAN WYK SAYING HE HAS NO POWER OF ATTORNEY WHEN IN FACT IT DOES SHOW ON THE ACCOUNT BECAUSE I CONFIRMED AT THE BRANCH WHERE IT WAS LOADED. THE MANAGER DID PHONE HIM TO COME COME BACK AGAIN AFTER HOURS TO ASSIST BUT THE INCONVENIENCE TO GO BACK AGAIN WHEN HE WAS THERE ALREADY IS NOT ACCEPTABLE. LIZ SHOULD HAVE DONE HER JOB THE FIRST TINE RIGHT. I DO NOT NEED ANYBODY TO PHONE ME OR APOLOGY IT SHOULD JUST BE REPORTED THAT *********** STAFF CAUSES CUSTOMERS INCONVENIENCE UNNECESSARY THE DAMAGE IS DONE
