Telkom cannot communicate

For a company whose key service is communication, they sure suck at it. I submitted an application form beginning May for a new voice line. They informed me that on the 27th May a service technician will be dispatched for a whole day appointment 07:30 to 16:00 to install a line at my house. I put in a days leave at work so that they would have access to my premises. The technician pitches up at 14:30, (so much for whole day appointment). He then tells me, there is no space on the exchange for an additional line.(Surely this could have been assessed before the on-site visit?!). They will upgrade the exchange within the next two days,then he will contact me to arrange another installation date. It has now been over a week. The call Center is of no-use at all, yesterday i spent 45 mins on a call for feedback. NOTHING!!! The technician who promised to call has not done so! The call center agents who promised to call, has not done so! The technical department who promised to call, has not done so! Telkom i am seriously disappointed.
