Incompetant technician

I've used telkom online chat during Januarie 2015 to request Telkom to check for errors on my line because it was slow. I did not request for a technician to come out to my property as I do not have the money to pay if it is something from my side and also did not suspect any faults physically. On Sunday the 17th of January a technician rang my gate bell and requested to enter my premises as I logged a fault. I said to him that I did not. He said that he then need to also enter to check at the box in the back of my premises for another residence. He then helped me without my consent to try and repair my line, while he was busy on the box he tested my line and came back to me and said that I must test my line as everthing looks in order. My line was then worse than before as it pinged before on 36ms and now at 186ms. He then said that I must take my router back because it is faulty and said that I must tell that lightning struck it. I took it back on the 21st of January to be tested and it tested to be in order. I've logged a fault on Sunday the 17th of January after the incident and still waiting for a technician. I cannot use my line and need to earn money with it.
