Bad Service Delivery

We had our lines suspended due to late payment, the bill was settled and an extra amount was paid in. 3 Days later I called Telkom logged in a call about the status of our lines and I was referred to the fault department on the 15/06/2015, they sent an sms as acknowledgement, 3 days later a technician came and the lines were fixed. 2 more technicians came after I had called twice again and the're still not fixed I sent an email to their \escalation"department till date Telkom hasn't done anything what's worse no one seems to know what the problem is with our lines. This is a business line and we cannot run business without our lines. Its going for a month and we still faulty lines. The part that frustrates the most is that they send sms saying our lines have been restored yet no one calls to actually confirm with us. """
