Terrible Service

I App**** for a new Line to be Installed on the 20/5/2015. Installation was scheduled for 27/5/2015 and there was an issue with where the line was to be Installed. Technician doesn't call to say he wont be doing the Installation that day, just leaves you to sit and wait for hours on end. <br> <br> I have tried to contacting the 10210 on a number of occasion to find out what is happening with the Installation and to date have not managed to even get through to an actual Call Centre Agent. SMS's state to view the appointment details online but that Application doesn't even work. What is a person supposed to do to service?<br> <br> If anyone actually decides to look into this the references are.<br> <br> 1. ***<br> 2. ***
