Telkom best in poor service - Missing appointments

Six weeks ago I app**** for a Telkom fixed landline (I currently have a fixed line look-alike) .When I followed up after 3 weeks, I was told that the order had been closed ... I then had it reinstated and a few weeks later received several SMSs informing me that the installation would take place on 8th July. I rearranged my entire programme and stayed at home the entire day, but Telkom did not show up. I then received an SMS informing me that the installation had been moved to today (15th July). On Monday I received another SMS confirming the installation time today and requesting me to also confirm, which I did. Today came and went, again without Telkom. Again I rescheduled my entire day and stayed at home all day.... Thanks Telkom, I lost 2 days because of you and you still have not delivered the service. I require a senior manager - somebody who can make things happen - to take on the responsibility to get this done - pronto. I am looking forward to your prompt telephonic response (less than 24 hours) and we need to get the installation done by no later than Wed next week. One more chance and no excuses.
