ADSL activation/repair

On 1 February 2015 I asked that my ADSL must be activated through an ISP thus Telkom was responsible for the activation. After two weeks the ADSL was activated but there was a fault on the line. Two weeks after this an technician eventually showed up to see what is wrong with the line. After identification of the fault it haven't been fixed to date. This is unacceptable and would like this matter to be settled as soon as possible as i am paying for the ADSL and the line hire but cannot use it because of the poor service.
