Line down for a month already

Our line has been down for a month already. Logged a fault on 26/02/2015 through the call centre with Maria. I phoned on 10/03/2015 to find out why it wasnt resolved as yet and Sibu told me she would phone me back in 2 minutes because the technicial was busy with a client. No phone call and the fault was marked as resolved even though our line was still not working. I then logged the fault again yesterday and phoned in and the consultant (Winston) promised me that the technician would phone me but a day later and still no call and the line is still down. This is absolutely pathetic. We are paying for a non existant service.
