NO OFFICE LINE FOR 3 MONTHS AND COUNTING

I reported my Business line faulty with Telkom on 31/12/2014, Ref. No: 109CKT***4. Weekly phone calls to their call center were met with same story, busy with the fault, line ******, will escalate etc. Now in March they advise that these lines are ****** regularly and will not be replaced. In the months since my reported fault, I have also been to visit the local Technical Services Branch in White River, also sent escalation e-mails to any e-mail address I can find and I have phoned weekly. At the Technical Services Branch in White River, you are not allowed into the premises, you are met by a security guard who gives you a note pad and you write a message in it. I have done that twice. No Telkom Technician has ever been to my offices, if they would do that, they would see there is another line on the premises that works 100% and a Technician could possibly just swap the two lines so that my voice/e-mail would work and I will sacrifice my fax line. If I had other options I would leave Telkom, but there are no other service providers in my area. What Now? I am spending a fortune on Vodacom to keep my business running.
