  • 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

  • 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

  • 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

  • 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

  • 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

  • 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.

  • 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!

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

    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

  • 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

  • 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.

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • 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. 👌👌👌

  • 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

  • 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

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • 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

  • cameron_kalani Cameron Kalani (@cameron_kalani) reported

    @O2 I've (it's actually my mum's phone) tried texting numerous times in the last 6 days, always getting some "can't be done now" message.. yesterday we phoned from the landline (because reception is so bad at theirs) and after 20 mins of holding, hung up

  • happyjack1981 Shauny—Bodhisattva (@happyjack1981) reported

    @Lorrainesleato1 @ThreeUK @O2 It’s been awful. Might be just where I live

  • David_Myint David Myint (@David_Myint) reported

    @O2 been in the USA since Saturday night. Have had no roaming data since I arrived. Been chatting to your support service since | arrived and all I can say is they have been useless. Appalling service and can't believe how bad your product is. Imagine not being able to roam.

  • M1ke_A Mike Anton (@M1ke_A) reported

    @tescomobile No phone signal in RH16. The @O2 network checker says they are doing upgrades until 27th! You don't offer WiFi calling so what are my options?

  • LoulouflyLouisa Louisa Lawrence (@LoulouflyLouisa) reported

    @O2 I put the code in but I put the wrong email so it never sent me an email

  • FionaTyler10 Fiona Tyler (@FionaTyler10) reported

    @O2 I've not been able to use my data for 3 days. I've been to Derby, Sheffield and close to Worksop. The only explanation I've found is a mast down in my area. I'm curious how large my area actually is now. Unable to find any other way of contacting O2 without writing a letter.

  • ceramaphee1 Ceri Jones (@ceramaphee1) reported

    So annoyed and frustrated with the Customer Service from @O2 It’s taken nearly 2.5 months to get an answer from someone and then it’s completely the opposite to what I have been told in the first place!! Not happy!!

  • vodkadebs Debbie Katy Seymour (@vodkadebs) reported

    @O2 have been trying to claim on my insurance for a week now, most O2web chat advisors are great however the one I have just had contact with… not so nice! Have been told claim team will be in touch, nope. Try calling direct and get passed around with no help! #O2

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @O2 @KEVSON1974 There you go, no commitment!! I have numerous messages over the last 4 months saying ‘we are addressing the issue’ means nothing

  • PaulDrivingADI Learn Our Way Driver Training (@PaulDrivingADI) reported

    @O2 Not sure I fully understand as I have used emoji’s on plenty of texts and not been charged. If your saying theses are classed as sending pictures. I will be looking to cancel my service and move to another provider
