No Accounts Received

The last account I received was for September 2015. No updates on internet either. Several complaints logged, e-mails to Tshwane Customer Care. Calls doesn't get answered. I pay every month an amount I think is correct. Meter reading for water incorrect on last account. Now just nothing happen. NO ACCOUNTS, NO internet updates on account. Why does these people just don't answer anything???? Calls or e-mails????
