What must we do to get service

I have moved premises and my telkom phone line and adsl was moved to my new premises. Since my i have had numerous problems with my phone line and adsl. A technician came out to fix my problem and my adsl worked for 3 days. Since I have reported the problem to telkom 5 times and every time they say it has been restored but for the past 2 months i have paid alot for my internet but can not use it due to no adsl. What must a person due to get a problem fixed by telkom. Is reporting the same problem 5 times not good enough. I am completely fed up and tired of paying for no service. How do you run a business with no internet for months??
