  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • stavros_mike Stav Michalis (@stavros_mike) reported

    Why is 4g and WiFi on trains so crap? @O2 @AvantiWestCoast You'd think with all the tech these days you'd get more than 1 bar Internet travelling through Warwickshire.

  • ConorJohnston Conor J (@ConorJohnston) reported

    Really disappointed by @O2 customer service. Being lied to on the online chat service, then when I called up and queued for over 40 minutes to speak to someone was told I'd be called back by a colleague within 10 minutes... That was over 90 minutes ago.

  • DaleLS4 Dale Livingstone (@DaleLS4) reported

    @O2 your advisers on the phone are an absolute joke and terrible service! How many people do I need to speak to to get a PAC code it’s a simple request. And don’t tell me to text for it because I have multiple numbers so need to ring and getting passed about departments!

  • choccieclare Emma (@choccieclare) reported

    @RachelOrr @O2 I am sim only. I am not fussed about handsets. I just need to be able to get phone calls and voice mails ! #o2 will never know how much stress they caused as the calls to try and get my voicemail failed

  • Serena_Symons Serena Symons (@Serena_Symons) reported

    @O2 have been trying to make a complaint & escalate my issue about no access to WiFi Extra. Which has been left for MONTHS. The technical team & customer services never call me back & no one seems to escalate to the Resolutions Department Why?! Time to leave?

  • SusanKelly673 Susan Kelly (@SusanKelly673) reported

    @O2 Seriously not impressed with length of time for unlatching code to be issued....and it doesn't work. I have a phone that's fully paid off. Cost a lot of money and I think it's wrong that you lock it to O2 network! Please unlock my phone...

  • tedmundsonbari Tim Edmundson (@tedmundsonbari) reported

    Is it possible to leave a network due to appalling service. Renewed my contract with @O2 and the service since has been dreadful. Intermittent data and having to constantly turn airplane mode on and off to get a data connection is simply, not good enough.

  • JoanneA47102663 Joanne Foley Anderson (@JoanneA47102663) reported

    @O2 why is it that we have 3 mobiles in our household that are on your network yet repeatedly my phone the only one out of the 3 is constantly on emergency calls only, even when the 3 phones are sitting side by side!

  • larrainesharri3 Larraine S Harrison (@larrainesharri3) reported

    @choccieclare @RachelOrr @O2 Good luck sorting it out Emma. I have just had to sort out a problem with them myself.

  • SiobhanL1993 Siobhan ❤️ (@SiobhanL1993) reported

    @O2 is o2 having problems? My internet hasn’t worked all day and my signal keeps going??
