Resolving of a fault logged on 5 September 2017 on my telephone line no ***.

I've logged a call on 5 September 2017 on my telephone line (landline). Line is noisy and have experience crossed lines. I've received a sms on my cellphone that they escalating the fault to the technical department. But it seems that there is no one in the technical departing because since then nothing happens with the fault. I could still make calls but it was very annoying and impossible to speak with the cracking sound in the background. The line is dead since this weekend and I can't receive or make any calls. I've tried to call to find out what's happening and when will the technical department resolve this problem, but I've hold for hours. Telkom's technical department is pathetic and there is no service from them. I must still pay for a service that I can't use.
