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

  • 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

  • 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?

  • 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

  • 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

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • 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

  • 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

  • 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!

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

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

  • 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.

  • 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. 👌👌👌

  • 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

  • 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

  • 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

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

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • Kerri_NM Kerri (@Kerri_NM) reported

    @O2 my phone service has been shocking for ages now (phone mast near me isn't working). Any ideas when this will be fixed? Your engineers have allegedly been working on it for at least a fortnight .

  • markjeapes Mark Jeapes (@markjeapes) reported

    @O2 24th August and use it for music and work calls, such good quality sound I’m really impressed and such good service from you guys

  • r_ic_k_tweets Rick (@r_ic_k_tweets) reported

  • FarrellHaylie Haylie Farrell (@FarrellHaylie) reported

    @O2 no service in Hull, is this a known issue? Checked settings and connectivity, still unable to receive signal.

  • markcottle17 Mark Cottle (@markcottle17) reported

    @O2 It’s all ba1 1ss it’s not busy it’s dropping to nothing and we are all having problems I’m paying for a poor service

  • Richard43249398 Richard Talbot (@Richard43249398) reported

    @O2 are so bad they have sent me faulty @Apple Air pod pros and they won’t even replace them. They won’t even send me a Jiffy bag to send them back. They just ignore me #Useless #PoorCustomerService #O2

  • markcoops20 Mark Cooper (@markcoops20) reported

    @O2 Part 1. So 13 days later and having been promised by tweet that the bill would be sorted I have just been sent emails threatening to penalty charge me as my bill is overdue. 3 bills produced that never got the figure to £0 and the top he emails saying I owe the full amount.

  • jamespdrury James Drury (@jamespdrury) reported

    @O2 can you confirm your complaints process please? Properly unimpressed with the process of leaving after you changed the terms for international roaming. Right up to calling first direct to cancel the £300 DD payment FROM THE MATERNITY UNIT after I was told it wouldn’t be taken

  • SueH4045 Sue Hetherington (@SueH4045) reported

    @O2 just had the most appalling customer service. Been with o2 for years and having spent 90mins on the phone today and been cut off twice I’m in off! Awful awful awful. Avoid
