BLOCKING THE LINE WHEN YOU WRONG

WHEN MY ACCOUNT WAS HANDED OVER TO ALTECH AUTOPAGE THEY NEVER LOADED DEBIT ORDERS AND MY ACC FALL IN ARREARS THEN I WAS ASKED WHY I NEVER CALLED TO FIND OUT WHY. THEN IN MARCH I MADE AN ARRANGEMENT THAT I WILL PAY R800 AND THE BALANCE OF R800 WILL BE DEBITED END OF MARCH I PAID WHAT I PROMISED AND A DEBIT ORDER WAS NEVER SET ON MY ACC. THEN LAST I GOT A BILL THAT I \OVER PAID"R800 WHICH I KNEW IT CANNOT BE. THEN MY LINE GETS BLOCKED AND I PHNE AND THEY APOLOGIZE THEN THEY UNBLOCK AND THEY SAID BECOZ THERE IS A DEBIT LOADED IT A MISTAKE. ON THE FIRST THEY ONLY TOOK ONE INSTALLMENT AND MY LINE IS ONCE AGAIN BLOCKED AND A RUDE CONSULTANT BY THE NAME OF MARCIA TOLD ME THAT SHE WORKS FOR ALTECH AUTOPAGE AND I MUST PAY MY ACCOUNT THEN THIS WONT HAPPEN. EVERY MONTH ITS THE SAME NONSENSE ALL OVER AGAIN. WHEN IT THIS NONSENSE GOING TO END. I GVE THE AUTHORITY THAT TIME TO DEBIT THE ARREARS BUT NOTHING HAPPENED AND ONCE AGAIN I SUFFER. I CANT KEEP MAKING ARRANGEMENTS AND HOW IS THIS AFFECTING MY CREDIT???"""
