    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

    @Gotham68 @O2 20+ years, 5 ongoing accs and they couldn’t, or wouldn’t, even lower my data on another account after I was mis-sold it. Waiting for my 5 accs to end contract so I can switch them to @SkyUK mobile too, counting down the days!

  • Natsynoonar itsme (@Natsynoonar) reported

    @paulbrookes171 @Gotham68 @O2 I get offered 5gb more data for extra £1/month cos I’m a loyal customer when I decline I then get offered a £1 per month loyalty discount for 24 months! The irony!
