Faults not fixed yet I still have to pay!!!

I have had the same problem recurring for the past fer weeks. Our line goes dead intermittently. My are is not even being affected by loadshedding that those times. I also have the battery backup covering the modem so the line stays up thru the loadshedding. I can't even call 10210 as they want me to when the problem occurs because of the dead line... I have logged endless calls just to have response later to say the line is up again... after a whole it goes dead again. Clearly they have not fixed the root cause. Please Telkom. Make a plan here.
