Inefficient service and no feedback

I am an existing customer and app**** for a DSL line installation at a new premises.<br> Date of installation was meant to be 07 April 2016. Problem #1: The appointment time (as per sms) was \Between 7:30 and 16:00\". Why exactly can you not give an actual appointment time? What about getting the technician to call first thing in the morning and let the customer know where the customer falls on the technician's list of jobs for the day i.e. first, last ?<br> While i was at work, my father waited at my house until 14:30 and then had to leave, the technician then called to say he was on his way. Therefore I had to postpone the appointment. A line installation is not something that i can, nor would i, take leave from work for.<br> <br> Problem #2:<br> Two consecutive phone calls this week, made to 10210, have led to my calls being dropped by the agents when supposedly putting me through to another team. Today the agent i spoke to said she put a note on the request to give me an update.<br> I have requested updates via the @TelkomZA twitter account, no luck there either.<br> <br> Extremely disappointing service after being a customer for a decade."
