Telkom Technicians can't setup modem

I had to 3x (yes 3x guys not just 1x) came to my house on Friday, 2 Feb 2018 to setup Telkom internet.

Asking me 2x to put my laptop into the modem and set it up, isn't it there job that they get paid for ?! What if I was a person that didn't knew at all how all of this modem and computer stuff works.

After spending the entire day there from about 11am till 4pm they left without my internet working and no modem being setup but with the response "there modem is working" and my modem is "not compatible with the Telkom network" even after I successfully used this modem on the same ADSL line with another ISP.

I came back the evening and a hour later the modem is working after I had to set this up myself. I am in IT so I do know how things work.

So what upset me here is:

* Am I going to get a invoice from Telkom for setup of my ADSL but then in the end the guys couldn't do it and I ended up having todo it successfully myself! * How many other Telkom customers does this happen too ? * What other none tech customers do your technicians tell this lie too that "your Modem is not compatible with our Network" meanwhile they actually can't do there work ?
