No phone line installation on agreed date

I app**** for a telephone line on 25 January(Monday) and got the sms Your order *** is scheduled for 2016/01/27 between 07:30 and 14:00, when I called them this morning at 08:30 the lady was clueless and told me i had to wait 7-14days for line installation. I told her it must be a mistake as I got the confirmation message and they were supposed to be coming today, the same lady who just told me there is no order yet to have the line installed told me that the tech indicated on his notes he had called both my phones and found no answer at 8:01 AM. Firstly i call ******** as I was on a landline phone from 08:01 till my call was answered at about 08:30 and had both my phones which he \contacted"me on next me(MTN & VODA). Do you want to tell me both of the numbers just did not work for those few minutes? This techie **** to his boss because I was never called!!!!. I would like to see proof which I bet he would not be able to provide"
