DICOVERY BANK CANNOT BE TRUSTED

THEY HAVE TAKEN MONEY FROM MY ACCOUNT. I HAD A CREDIT BALANCE ON THE OLD DISCOVERY CREDIT CARD - WHEN THE DISCOVERY BANK OPENED MY BALANCE WAS BROUGHT FORWARD AS NIL. HAVE EMAILED AND CALLED ON NUMEROUS (11 OCCASIONS) BUT STILL NO RESPONSE OR SOLUTION. THEY KEEP TAKING MONEY OFF OUR ACCOUNT - WITHOUT SIGNED CONSENT (OR ANY CONSENT FOR THAT MATTER). I HAVE A CASE NO BUT THAT STILL DOESNT SEEM TO HELP. THIS HAS BEEN GOING ON SINCE - JULY 2020. JUST CANNOT GET ANY HELP. NEXT STEP IS OMBUDSMAN AND LAWYERS
