    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • 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 👏.

  • 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!

  • 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

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

  • 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

  • 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

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

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

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • cove123 mark nicolson (@cove123) reported from Welwyn Garden City, England

    @O2 opened app to use bacon sandwich offer local greggs not open yet for some reason @GreggsOfficial Wgc poor

  • 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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • 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

  • LauraaNicolee_ Laura🦋 (@LauraaNicolee_) reported

    @O2 I need to change the bank details on my account, tried to phone customer services but the wait time is over an hour. Is there any other way to do it or a quieter time to ring. I need them changed before Monday

  • brownzoju Zoe Brown (@brownzoju) reported

    @O2 Hi @O2 ive still not had any reply or advice on how to cancel a contract from abroad. I will therefore cancel my direct debit and please accept this as my cancellation.

  • RanKotobukiii 👸🏿 (@RanKotobukiii) reported

    @O2 @lastminute_com If the blink takes 20 minutes on hold, like your customer service......

  • WayneyoWayne wayne Tavit (@WayneyoWayne) reported

    @Ofcom What rights do I have as a contracted customer of @O2, if their service has been poor for the last 5 months?

  • B0BF0551l BobFossil (@B0BF0551l) reported

    @O2 stat for the day: I’ve wasted 4 hours of my life this month on hold to you. Trying to reconnect my Apple Watch (after an Apple service) and then to cancel a cancelled line you keep charging me for. Calls dropped Or staff that don’t care. You used to be better than this.

  • scottather1998 Scott ⚡️ (@scottather1998) reported

    @O2 @virginmedia sort it out. Signal and Connections at the moment are ****

  • WayneyoWayne wayne Tavit (@WayneyoWayne) reported

    @O2 can you take me through your official complaints procedure please, so I can escalate it to the industry moderator. I have had intermittent service since November, which I believe is unacceptable.

  • Boothyccfc Craig Booth (@Boothyccfc) reported

    @O2 I'm having problems activating my O2 Amazon prime benefits, and can't get through to speak to anyone via chat or phone, also they have given me 4 days to activate..

  • WezG Wez G (@WezG) reported

    @DHLParcelUK your telephone line is broken - nobody answers and in the automated part that is only place I seem to get to it terminates call midway through entering parcel number - is there any way at all of contacting DHL ? @o2 confirm parcel is arriving today - is it?
