STANDARD BANK SERVICE DETERIOTATING -BAD TO WORSE

I AM BANKING WITH STANDARD FOR OVER 30 YEARS. I PAY CLOSE TO R200 PER MONTH HOPING TO GET A BETTER SERVICE VIA PRESTIGE BANKING BUT ALAS.. THE SERVICE IS WORSE. I AM CONSIDERING TO DOWN GRADE MY ACCOUNTS TO ORDINARY AND JUST FOLLOW THE QUEUES TO GET PERSONAL FACE TO FACE SERVICE. SOME PEOPLE STOLE R4000 VIA A STANDARD BANK LINK - I IMMEDIATELY REPORTED IT.. STANDARD BANK DID NOTHING ABOUT IT - I THINK THE PERSON WHO WAS HELPING ME ON STANDARD BANK WAS A ***** HIMSELF. WHO ELSE CAN WE REPORT SUCH BANKS TO. AS FAR AS I AM CONCERN THEY SHOULD REFUND ALL MY MONIES I PAID FROM PRESTIGE SERVICES AS I HAVE SENT MANY EMAIL COMPLAINTS BUT THEY JUST IGNORE THEM.
