3rd Time and line still not installed - NEED LINE

This is know the 3rd time the technician did not pitch to install the line ordered on the 20 Aug 2015. I have phoned numerous times and have escalated the order 3 times already and posted a complaint on Hello Peter. I urgently need this line for my work. I just spoke to the support chat and they just said the install date was changed again with out any sms or phone call whatsoever. When I asked fo the reason they say they cant give a reason. <br> <br> You should check your installations department and if staff don't want to do the work get rid off them. This is hurting your brand and your company. Can a Senior manager please contact me regarding this matter . My install ref number is ***A. I need this resolved asap. My Adsl line is also on hold because off this
