Why cant you just do what you guys promise?

It's been three months trying to install a line with Telkom then you guys keep getting my address and detail wrong then after spending countless hours in queues I finally get an installation date 05/11/2015 I then book leave after making sure so many times that everything should go as planned I then wait patiently at home as the booking says 07:30 till 04:00 I keep phoning during the course of the day and Telkom keeps assuring me that everything should be fine at 15:30 the engineer gives me a call to say his outside, then leaves again in 5 minutes saying that Telkom gave him the wrong detail he can come back tomorrow to sort out the issue before 12 the next day then me obviously questioning the statement starts to get into an argument because if it can be done the next day then why can't It be done now so the engineer then just states in that case ill just send the issue back to Telkom and you'll have to wait in the queue again what kind of service is that how can you treat people like that? I then asked him for his name and he refused. Why could this guy's sort out the problem the next day? Ord ***
