    @O2 eventually got my pac code after a long two weeks although all you get is a petty ‘sorry for the inconvenience’ leaving customers financially impacted with such a petty apology. Really unhappy with the service

    Quite sad that you contact @O2 about network issues and how it doesn’t reflect their coverage map at all and their answer is simply “tough” all of our #Bracknell masts are all out of service indefinitely for upgrades that may or may not be happening.
