Appalling service

I just had a billed voice line installed and the consultant just called me to ask if it has been installed. I said yes and asked the consultant when I would receive a bill or invoice or confirmation of some sort, since I haven't received a single message or call to even tell me when the technician would come, which was promised to me before when I asked for a reference number. My concern was that Telkom would mess up my order, because I didn't want to wait until 30 days went by to receive a bill and then we were making billed calls, under the assumption that they were free. I then asked them to check if the voice package which offers free calls at night and over weekends has been added as requested, he said yes, I then asked him which times these calls needs to be made in order for them to be free, he then said I can call anytime between 7am and 7pm to which I responded that 7am is the morning and not the evening. He says yes. Again, I explain that I requested free calls at night and not during the day and he says he needs to call me back to confirm. At this point I'm confused, because he could just tell me that I had free calls from 7am until 7pm, but now he's telling me that he needs to call me back. So I ask him to explain, he goes quiet and hangs up. Can someone please explain this disgusting encounter I've just experienced?
