Telephone out of order for 6 weeks

Our Landline has been dead for 6 weeks. We reported it on 9 July 2015. To date we have had one technician who could not fix the problem and said he would return the next day and he is still coming. We have phoned and 'sent 'text messages and we are informed that a technician has been assigned but no joy. we are paying rental for no service. This is unacceptable both as regards the service and the rental<br> <br> Stuart Carstens
