Discoverys unjustified harassment

FOR ALOMOST 3 YEARS I HAVE BEEN HARRASED BY DISCOVERY AND ITC TO PAY AN ACCOUNT I HAVE NO IDEA WHAT IT IS FOR. WHEN I REQUESTED A STATEMENT TO SEE WHERE THEY GET THIS FROM NO ONE CAN PRESENT ME WITH IT, BASICALLY INSISTING I PAY NEARLY R10 000 FOR SOMETHING THAT THEY NOR ITC KNOW WHAT FOR. AFTER BEGGING AND PLEADING FOR ALMOST 3 YEARS I STILL HAVE NOT RECIEVED ANYTHING FROM EITHER PARTY. THIS HAS MAJORLY AFFECTED MY CREDIT SCORE. I STRONGLY ADVICE AGAINST USING SUCH SERVICE PROVIDERS AS IT CLEARLY SHOWS THEY ARE TRYING TO ********LY GET PAYMENT FROM INDIVIDUALS WITHOUT PRESENT ANY SOURCE OF PROOF IN THE FORM OF A DETAILED STATEMENT. I WILL BE TAKING THIS MATTER TO THE OMBUDSMAN. FURTHERMORE THEY INSIST I PAY FOR ALL THE CALLS MADE BY ITC HOWEVER I KEEP BEGGING THEM FOR A STATEMENT AND THEY NEVER GET BACK TO ME FOR MONTHS THEN A NEW AGENT GETS MY ACCOUNT AND CALLS THEN WE START THIS HARRASMENT CYCLE AGAIN.
