Technician has purposely sabotaged my line

I reported a fault in my line last Wednesday. I wasted the entire day on Friday with a technician who eventually fixed the line outside. Then today, I received a call from a technician called Murray who called me sweetheart and told me that there was an issue with my line. I told him that the issue had been fixed and I have Internet. He then told me no, I am wrong and hung up on me. I have returned home late this evening to find that this technician has purposefully disconnected my line! I have no internet again! Please can Telkom urgently attend to this ********** activity and more importantly fix my internet properly.
