    @EnglandRugby @huntie_1 @O2 I've never been to ******. I don't think I'd like it at all.

  • danmarr Daniel Marr (@danmarr) reported

    @GlennSmithF1 @O2 Yep, they keep lines open, even the ones that are mis-sold, preventing the customer from getting pay monthly. The customer is punished twice, once with the mis-selling and a second time by restricted access and credit checks

  • OzzyD_en Oliver Dixon (@OzzyD_en) reported

    Never going to @LidlGB again if I can help it. What an ordeal! I need therapy and a lie down now! 😡😡 while I'm at it, @O2? You CAN be replaced! ... how can one shopping expedition go so horribly wrong??

  • Travellingsanta Arvind Ramesh (@Travellingsanta) reported

    @O2 I am absolutely disgusted to inform the level of customer experience offered which makes me feel grateful of moving my network provider elsewhere. I was disappointed to have been rejected for credit applications stating my credit score to be very poor for the same.

  • Nehakedia2014 Neha kedia (@Nehakedia2014) reported

    @O2 i ordered a replacement sim, but not able to activate it, please help

  • pengetoanywhere Becca Jones (@pengetoanywhere) reported

    @O2 And yes, I was assured by 2 members of your customer service team it was all done on Thursday morning. I’ve never had this issue before, it’s been a total pain not being able to use my phone (despite still paying for it 🙃) it’s just not good enough!
