Bad, bad, bad service

I lodged a complaint about two weeks ago about Telkom's bad service. I got an immediate response, promising me that Telkom would look into the matter and come back to me. I am still waiting for their feedback. In the meantime, we have spoken to Telkom on various occasions, asking them when they are going to connect the line to our new office - the first promise Telkom made was '2 days', then 'within a period of 7 working days' and at last, we received an sms yesterday to say that they will be coming today, 9 days later. When the technician arrived today, he told us that we are in another area than previously, and will now have to wait for 3 weeks! We have spoken to Telkom various times, I have written an email with both addresses (old and new) to them on the 31st of August, both offices are in the same mall, just opposite sides, and after a period of nearly six weeks since I have started this process, they only realise NOW that we are in a 'new' area. We are running a business and URGENTLY need a Telkom line - but who cares? Definitely NOT TELKOM.
