My wife and I have only been with O2 for 3 months, but so far everything is perfect! Good signal, good deal on the new iPhone 5 and now we have decided to use their broadband service (Instead of Virgin Media's terrible broadband). O2 seems competent, friendly and has very friendly staff. Whenever I deal with them I go to their store on 286 Chiswick High Street. It is a bit out of my way, but the staff there is fantastic and they deserve 90% of the credit for making us stick with O2!
