No Business Line for Weeks

I reported my landline to be non-functional (completely dead) - Telkom tested it and confirmed there is a problem. Each consecutive time Ive phoned Telkom they just log the fault again and tell me there is nothing they can do further but the line is still being tested - what could they possibly test for this long - its confirmed: the line is faulty. The supervisor I asked for never came to the phone. The technicians who committed to escalating this issue I never heard from again. 95% of my business is conducted on the phone - not having a landline even for one day is disastrous to my business. On top of that Telkom is still charging me for this non-delivery - WHICH I WILL NOT BE PAYING FOR TELKOM. Your lack of interest is unacceptable.
