How do you guys survive with service like this

In early February we app**** for a new ADSL line for the offices we moved into. An appointment was set for the 26th of February (> 2 weeks wait) and this was confirmed via SMS.<br> On the 26th, I received an SMS in the morning telling me that a technician had been dispatched to us.<br> At the 3pm the same day I received another SMS telling me again that a technician had been dispatched.<br> But no technician arrived.<br> The next day (after waiting for about 20 minutes to talk to someone) I was told that the technician couldn't find our premises (which is ridiculous) and another appointment had to be made.<br> Since then I have phoned the Telkom call centre (10217 and 10210) every business day and have been told every day that the matter has been escalated and someone will contact us with another appointment date. On Monday the 9th of March I was eventually told to email the escalation centre with my references which I duly did and after receiving an auto reply that they will attend to my matter as soon as they receive my mail (which they clearly did because they answered it) I have heard nothing.<br> We are trying to run our business here - can you PLEASE sort this out.
