QUICK BILLING, SLOW ACTIVATION

I renewed 2 contracts on 20/09/2015. Was sent 2 new phones along with 2 new LTE sim cards, with specific instruction on how to activate the sim. Called *** to activate sim only to be advised that they are experiencing problems and to try again later.This went on for 4 days until I eventually called the call centre to advis that there is a permanent problem with the activation line.Initially the gentleman was very friendly and requested the 2 sim card numbers and assured me that he has activated the sim.Advising me to switch off phones and try them in approx 2 hours.Alas, after 2 hours no activation, after 4 hours no activation, after 6 hours no activation!!!! Tried last time on Monday morning, 48 hours later, still nothing. Called call centre and this is when the running around started. Being advised that there is nothing that can be done unless I reboot phone and IF not working to call back. Called back, spoke to different person, given something else to do and so it went on. Finally, I have sent mail to have contracts cancelled as a result, still no response.<br> Seems like I know a lot more than the current staff at call centre.<br> Still awaiting response from either
