No service on telkom line

For the last 3 months at least I have had endless hassle with connectivity on the telkom line ***. I derive my income from being connected to the internet 24 hours a day and have suffered loss with the service received from telkom. December month alone I have had no connectivity for half of the month. The line was disconnected during December because telkom made a mistake on my line and thought I was in arrears with the account. Then on the 21st of December the line was switched off again and up until today I still don't have an active line. I have reported the fault - ref number 150ARK211215 on the 21st of December. I have been in contact with telkom who tells me the same every time, as soon as a technician is available they will contact me. I am upset as well because I have to pay for a service I am not receiving and would like a discount on the amount due to make up for the loss of income I have had to suffer during these 3 months
