Technicians decide to lie

I was informed by a Telkom technician and supervisor that my line would be installed today (4/3/2015). I had to cancel my entire day's class so I could by home when the technician would arrive. However, I was notified that the technician was here and according to him no one was home, which I find strange as I sit less than a meter away from our front door. I don't understand why you feel it is necessary to lie to a paying customer. I find it unacceptable behavior from a leading service provider like yourself. And what is worse is the customer care. When we tried to contact the supervisor we discovered there is no cell number connected with her, she only communicates in email. So thanks to incopitence, lies and just plain lazyness I will be without Internet for probably the next few weeks, if this is the way things are done.
