  • bection Rebecca Faulkner (@bection) reported

    @O2 But I never had this issue before 5g came in. I'm paying a high rate for terrible service. That's not acceptable

  • SusieTullettPR Susie Tullett (@SusieTullettPR) reported

    @O2 I am beyond incandescent that after almost 30 years of loyalty to you, my service is cut off with no warning??!!! OK |I was a little late paying, but there was a good reason. Did you check? Did Customer Services wonder why I was unusually late paying? It is now paid.

  • tariiscee Shumbalette (@tariiscee) reported

    @O2 customer service is shocking and in a horrendous way !

  • teh_c Chris (@teh_c) reported

    @O2 I initially phoned and was promised a confirmation email within 24hr -- never received. So I used live chat and got written confirmation and was advised to cancel DD. Then you emailed me last week saying I owed you money. Phoned to get that credited to the account. Now this.

  • BarryStump BarryStump (@BarryStump) reported

    @mynoseisblockt @O2 o2 is the worst i have ever known for customer service I have downgraded on my website to D ( unrated)

  • rt1979rt Rich T (@rt1979rt) reported

    @ArcticReviews @O2 It’s terrible isn’t it. Zero empathy and pathetic justification for increasing the price. I’d also argue that the CPI should be used rather than the RPI. Not sure how either impact O2’s ability to investment either.

  • FredSmi22494411 Fred Smith (@FredSmi22494411) reported

    @O2 Anybody else having text message problems????

  • Slim5hdy 🏴󠁧󠁢󠁳󠁣󠁴󠁿Andy McCrorie🇬🇧 (@Slim5hdy) reported

    @O2 I have done this but it says network fine in the area , I’m currently connected to the bus wifi to post this reply 🧐

  • ZacharySnell6 Zachary Snell (@ZacharySnell6) reported

    @O2 is your network down as I have no service ? Thanks

  • Katie_t_cat Katie (@Katie_t_cat) reported

    @O2 Is there nothing you can do to stop the tide of scam texts and phone calls? Surely if someone sends hundreds of similar texts from a spoofed phone number you must be able to detect that and block them? I know other countries can at least give a warning on screen to help…
