Interrupted / No Service

My landline number *** works randomly and shuts down randomly. After numerous calls and speaking to an automated system for days I would like to know what Telkom plans to do about the situation and how soon will this service be restored? When they do get it together and send a technician out to deal with this issue , we have service for a day and then the it stops working, when we have to call again from our cellphones to report the problem and wait another few days for someone to respond. So in the meantime while this line is not functioning we are still being billed for line rental, (what rental I would like to know) as there is no service. Please can we have this matter resolved so we know why we paying line rental because we are currently paying for a dead line.
