  • 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

  • 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.

  • Pretty_Gorge A dollop of kindness (@Pretty_Gorge) reported from London Colney, England

    @O2 on your live chat for 15mins about fraudulent activity on my mobile account. Can someone help?!?!?!

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

  • 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

  • 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

  • fierce_unicorn 🦄 (@fierce_unicorn) reported from Enfield Lock, England

    @O2 merlin pass code is not working, can you help?

  • 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. 👌👌👌

  • 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

  • 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 👏.

  • 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

  • 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

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from London Colney, England

    Is there a hashtag for awful customer service from @O2 and/or @DHLParcelUK ? Asking for a friend.

  • peterives50 Peter Ives (@peterives50) reported from Enfield Lock, England

    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • 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

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    £105.03 A MONTH AND FOR THE LAST 6 MONTHS NO NETWORK !!! @O2 DO BETTER

  • PieFaceMark mark (@PieFaceMark) reported from London Colney, England

    @O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

  • shazzstevo Sharon Stephenson (@shazzstevo) reported from Enfield Lock, England

    @O2 My calls keeps dropping. This has been happening for several days now. This is really poor service. This is in the Enfield area

  • 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

  • alisonjyoga Alison Johnson (@alisonjyoga) reported

    @O2 #o2 Hello. I have the same problem again with my mobile trying to use my Data in France Basically I can’t use Data. I can only use my phone when I can access WiFi. Not great in France as public WiFi very limited. I’m relying on my phone to keep up with work

  • xKatiex_ Summer Fence (@xKatiex_) reported

    @O2 I’ve had my contact three months and in that time your service in my area has been down more than it has worked. Trying to get through to someone, no hold message and rings out. Can’t use webchat as says you’re too busy. I need to speak to someone to cancel please

  • SteveMacpompey Steve M (@SteveMacpompey) reported

    @O2 Why is trying to buy anything from you guys (a simple data SIM) so painfully slow and laboriously frustrating? After 30 mins inane chat I just gave up and jumped off a bridge!

  • D4N7O DAN. (@D4N7O) reported

    Anyone else on @o2 unable to make calls? My mam on @tescomobile having the same problem?

  • Socia11yDistant Still Socially Distant (@Socia11yDistant) reported

    Huge regret moving to @O2 signal in my area is 100% not as shown on their coverage map. It's absolute DIRT Should have stayed with @ThreeUK

  • TonyChapman1 Tony Chapman 🐐 (@TonyChapman1) reported

    @virginmedia is a pile of horse ****, worst internet provider in wd5 area always going down for long constant periods, but they still want to charge a fortune for its service, got worse since it paired with @O2

  • ianrosenthal Ian Rosenthal (@ianrosenthal) reported

    @O2 Why is swapping a phone number from an old sim to a new one so difficult. Have tried 3 times in the last month. Website, calling customer services and the move by text service all told me that I'll be moved within 24 hours. 48 hours since latest attempt and still nothing.

  • BW_evo BW (@BW_evo) reported

    @EnglandRugby @dannycare @O2 Should never have been kept out of the squad! Lunacy.
