Lack of service since November 2015

Throughout 2015 I have been complaining about the intermittent voice service on my home Telkom landline. The problem was that I could not have a conversation for more than a minute and the phone would cut. After reporting the matter more than five time throughout 2015, in October the ADSL service also started not working properly. Every time I logged a called I would arrogantly told that the matter was fixed yet it was not. I reported the matter online on the 27 November. Nothing was done. I then went to the Menlyn branch to physically complain on the 17 Dec 15. I was told that they would fix the matter that same afternoon if not the next morning. Nothing happened. I went on holiday for two weeks only to return to further frustration of a lack of service. I am upto date with payment of my account which makes me expect service for the hard earned money I pay for the nine service delivery. I returned to the Menlyn branch on the 4th January 2016 to enquire why I still did not have service and I was told people were on leave over the past week and I would have to wait my turn this is despite having been serviced since 27 Nov 2015. What else must one to do to get service from Telkom.
