Telkom - The waiting Game

I placed orders for transfer of lines on the 14th August 2015, a technician was suppose to be here on the 31 August 2015 to install new lines and we still waiting. Not only can they not tell me how long it will take for the technician to arrive and sort out my business lines but they have now dis-connected my old lines which I had diverted to our cellphones in order for our clients to be able to call us. I am in-raged with this situation and at my wits end with Telkoms so-called service. Why is it always the BIG companies that mess us around so much.
