  • 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

  • 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

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

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

  • 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?!?!?!

  • 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.

  • 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

    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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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 👏.

  • 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.

  • 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 😡

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

  • Ian02375771 Ian (@Ian02375771) reported

    @virginmedia @O2 I wonder if customer service at 02 is as bad as virgin media? Been waiting a month to be connected after connection date. I ring but no one knows. now I just get passed on until the phone gets put down. 30 reschedule appointments. to say this service is poor is an understatement!

  • Duncan_Leeds Duncan 🙏 🇺🇦 ❤️ 🌻 (@Duncan_Leeds) reported

    @virginmedia @O2 Match made in heaven - don’t think so. Told my pretty basic package goes up from £60 to £75, yet a new customer can get a better package for £29.99. Phoned to ask if I could have the same & was basically told to bugger off. Not much point sticking around then. Off to @EE we go…

  • Jas_Pn Jas Pn (@Jas_Pn) reported

    waiting in a queue for 1 hour 3 times, where @O2 have hung up during the conversation. 3 hours of my day gone! worst customer service

  • gingerdanny1 Daniel Parsons (@gingerdanny1) reported

    @O2 your online help is a joke.

  • Banjomeister Sanj Johal (@Banjomeister) reported

    @O2 So waited all day and nothing. I've only been in touch with you since January about these issues and still not sorted despite being told you would get back to me when you can. #transplantpatient #O2terriblecustomerservice

  • buchananballs Adam Buchanan (@buchananballs) reported

    @O2 My Wi-Fi is running a stupidly low speeds but I’ve arranged to get that sorted, please can someone explain why I’m getting no 4G as your not providing me with the service I’m paying for and surely that a breach of contract ?

  • solalmi Sonsoles A. Miguel (@solalmi) reported

    @O2 terrible customer service. I requested a phone number transfer last Friday and still hasn’t happened. Now the ******* the chat says my partner needs to call you again to raise another enquire as the data provided was wrong, but the guy on the phone said everything was ok!WOW

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported

    @O2 There is an issue with the page for accessible tickets. It may be that they're sold out now idk, but the drop down menu for wheelchair spaces is glitched I think, & that affects the menu for ambulatory spaces. And the seat map is glitched half behind the menu too

  • shannont90 Shannon Turner (@shannont90) reported

    @O2 I've had no signal for almost 24 hours now, I'm running on wifi. Online says it will be fixed by Saturday 18th. Surely not?

  • Antonferrari36 AF (@Antonferrari36) reported

    @O2 we have a business package and have just purchased a new personal contract, called customer service and hung up twice. Went to 02 store in upper street, worst customer service ever, totally dismissed. Simply want to migrate a number. Will be handing back new phone immediately
