Frustrating Service

We ordered an additional Telkom line almost a month ago , Telkom promptly sent an sms stating that the line would be installed on the 1st of October (Today) between 7:30 and 16:00. I took a day off from work so that I could be home for the installation. No one showed up at my house, no communication was received, no explanation NOTHING!!! I called the Telkom support line looking for answers and the correspondent sounded very disinterested and could not give me a valid reason as to why the technician did not show up as promised. This is ********** service and a bad representation of the company. I feel like Telkom does not value their customers as they have very little competition out there. I find this very frustrating as i am a long term client with the very same company that is treating us like we mean NOTHING to them.
