TELKOM POOR SERVICE

I registered a fault with my landline with Telkom on 14 March 2018 and have followed up with many telephone enquiries,as to the progress, and several visits to their service centres but to date the landline is STILL out of order. Each time I am told the matter is "receiving attention" and lately I have been informed it has be escalated. I hope I will only pay pro rata service fees for this month since I have not had the full use of my landline. Originally I thought the problem was with the handset as I have not had any use of my landline since the beginning of the month and bough a new handset only to discover that the problem was still the same. That was when I contacted Telkom to lodge a fault. Some family and friends have also called Telkom to report the fault. I dont receive courtesy calls or sms messages to inform me of the problem. I run a home business and advertise using my landline number although its not a business number but some people prefer calling on a landline. Can anyone tell me what the average time is for Telkom to attend to a faulty line.
