Pathetic service! Disconnected my line on a Saturday morning, called tech for assistance but wouldn't assist me because for some reason the security question of my nominated contact number was some number I have never heard of and they refused to take my correct information which has never been a problem in the past as I have called them many times before... Argued with them for around 5 hours until I was informed nothing can be done within the next 72 hours
