No service since Aug

My house voice line has been out of service since August. I have a reference number but nothing ever happens. If I call faults I'm promised a team leader will call me back but never does. You continue to send me bills covering the period I had no service but to actually come to my house and fix the phone that you seem incapable of. Your customer service and after sales service is non existent. I see you were exposed in The Star two days ago for repair incompetence. This is another such incident. Get your act into gear and fix people's phones. What's wrong with you?
