    @O2 Unfortunately I’ve tried various things, including being sent a new SIM card, and I still have this recurring problem.

  • Markyboy7104 Mark 🇬🇧 🇩🇰 🇪🇺 (@Markyboy7104) reported

    @O2 Your sales and customer service team are denying my request to become an O2 customer because I live inside a military establishment (registered address for everything) else . Is this #Britisharmy discrimination by O2 Can you assist where your branch & CS team can not?

  • 3atcat Batcat (@3atcat) reported

    @O2 I’ve been charged £42 for 10mb of data in a country ive never visited - this has quadrupled my bill, looking for some help

  • myearley86 Martin Yearley (@myearley86) reported

    @O2 Shocking coverage as usual. Showing full 5g signal yet nothing is loading.

  • Markyboy7104 Mark 🇬🇧 🇩🇰 🇪🇺 (@Markyboy7104) reported

    @markevans02 - pretty disappointed as a hopeful customer of @O2 to be denied because I am a member of the #UKArmedForces that live inside a military establishment that is a genuinely registered private addresses its residents. Especially as O2 is a member of #armedforcescovenant

  • ImJacobHughes Jake Hughes 🇬🇧 (@ImJacobHughes) reported

    @_DanielWalsh_ @O2 Still nothing, customer service was supposed to give me a call on Friday but that hasn't happened either
