    @O2 They’re acting as o2. Perhaps your legal team need to get involved as they asked me as an existing o2 customer (which I’m not) if I’d like offers on top of my tariff. I asked where they were calling from and they said O2

  • AlfEyyyy Alf (@AlfEyyyy) reported

    @O2 Should’ve made that clearer. There were no exceptions or caveats in the banner, or mention it was devices only - only time it was communicated was after the order was completed. SIM won’t reach me in time before I travel so have to cancel(which in itself is an arduous process 🥺)

  • MariaC_____ Maria Carruthers ღ (@MariaC_____) reported

    @O2 Sorted it thanks.I have another issue now.I was sure I changed my address when I moved in 2019.Just ordered a phone but my bill needs to have my current address as proof.I've changed it now but can't wait a month for it to show the correct address.Can anything be done about this?

  • squattingdug John smith (@squattingdug) reported

    @O2 None of that helped, probably because the problem is simply the signal strength is terrible here, how do I cancel my contract? As its not fit for purpose.

  • eva83481607 eva (@eva83481607) reported

    @O2 I am so confused how to use my phone when in the US! I have O2 travel bolt on but I received texts that I went over my data limit (which I didn’t even know I had). Help! I don’t want to get loads of charges by doing something stupid

  • Sweetiee75 _sweet1 (@Sweetiee75) reported

    @O2 can you please fix your website. I’m trying to purchase Apple Watch and it crashes when I try to select continue as an existing user. I’ve tried 3 different devices and internet connections

  • EllieAn85053441 Ellie Anderson (@EllieAn85053441) reported

    @O2 Calls and texts have never worked since I got out here, hence why I’m relying so heavily on data for safety reasons!

  • Jayenkai Jayenkai [JNK] (@Jayenkai) reported

    @GeriatricGamer @O2 My last £10 PAYG top up (last feb, IIRC) is now down to a shockingly low £2.29 *gasp* .. They're definitely not sending me a new phone for that.

  • nshstj just me.... (@nshstj) reported

    @O2 how do i speakto a human at o2! Iv been trying all day. Automated keeps cutting me of. Start chat sends a list of questions then refers me to community. Iv had enough an want to cancel my contract now. It used to be easy to tlk to a human, not anymore

  • JoJoTFB Joooooooo ♥ (@JoJoTFB) reported

    @O2 Hi, I was just looking at the Odeon cinema offer on priority and it says unavailable as I have hit my redemption limit. I haven't actually used a code due to the movie not being out and had planned to use a later option. Is it possible to fix this?
