no landline and no internet

I reported a fault om my landline and internet line for the first time on 12 August 2015. My telephone number is ***. Telkom has been to my house in Greymont, Johannesburg twice, to declare that the fault is nott in my house, but up till now they have not been able to repair either the landline or the internet line. The landline now is connected and it even rings but there is so much creaking on the line that it is impossible to use.
