In spite of the serious inconvenience this incident has caused (in today's world we rely very much on our smartphones and technical failures such as this recent one can seriously dent the productivity of a working day), no provider will ever guarantee a failure-free service. But this is not the issue here. My problem lies with the lack of communication and total absence of a contingency plan to keep customers informed and help them alleviate some of the issues resulting from the interruption of service. This could include : - ability from O2 website “My O2” to divert calls to another number (during the breakdown, there was no voicemail, so we have no way of knowing who tried to call us during that time) - info on website on how to circumvent some of the problems re calls, internet access etc… - system to inform all O2 shop staff (maybe put poster in shop ?) - emails to customers (many of them working at computer, not all “out and about”) - generic code to use Wifi in O2 hotspots (to avoid the need for new users to register and not receive their code by SMS when the 3G system is down !) It just strikes me that O2 are prompt to send emails to their customers to promote offers etc. Why not do the same just to let people know they are experiencing a problem, so that hundreds of thousands of users don't worry about their phone being broken ??? I feel sorry for O2's staff who were evidently given no information nor instructions on how to deal with the matter, leaving them confronted with a bunch of angry customers with no means to help them. The little list above would have made such a difference ! Any company that does not have an emergency contingency plan is miles away from best practice. I am more concerned about O2's lack of professionalism in dealing with this matter than the technical failure itself, which could have affected any other operator. They need to get their act together from a managerial point of view, and let us know when they think there back-up plans are ready for the next time something goes wrong. Because one day, something similar will happen again, that's normal. It's only a question of time.
