Non Delivery and Adhering to Dates

I ordered a uncapped ADSL line.<br> My Wife is busy with honours and all her material is online. i am currently using a ****le but it is not consistent and frustrates her,<br> I ordered a ADSL line to combat this and i knew there is a waiting period.<br> Received a message that my installation is scheduled for today 2016/02/10 between 7:30 and 16:00.<br> Had to take off a day from work even though in my industry it is extremely hard to do so.<br> at 4pm and i received no phone call or message regarding the installation.<br> I will not be able to take off work any time soon again and it is difficult to have someone available during the day.<br> I am extremely frustrated and annoyed.<br> I do not mind waiting but if you state that services will be delivered on a day, then please adhere to it, because i have no idea what i will do now.<br> Highly annoyed <br> Received a message at 4:30pm that technicians are on their way and still nothing and its 5:30pm. I mean i am my wife's lift home from work and she is now waiting because i have no idea if the technicians are still going to pitch up.<br> Very unprofessional<br> Very unreliable
