  • 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

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • 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 👏.

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • 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

  • 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

  • gadgetgem Gem (@gadgetgem) reported from Barnet, England

    Missed out on my free sandwich this week @GreggsOfficial with @o2 due to the scanner being broken again. Went to next nearest greggs and they had no breakfast 😢 #o2priority #greggs #breakfast

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

    @O2 merlin pass code is not working, can you 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.

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • 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

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • 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

  • 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

  • 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.

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • VictoriamariaC Victoria Clarke (@VictoriamariaC) reported from Walthamstow, England

    @O2 please can I ask why you have left a 76 women who has just lost her husband and undergoing cancer treatment without any phone service and no one is able to help. Absolute disgrace @lec1479

  • 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

  • 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

  • debswild DEBS WILD (@debswild) reported

    @O2 Wifi calling is awful when calling landlines which is what I was doing when the issue occurred.

  • bjorn6 Michael Walker (@bjorn6) reported

    @PatrickMcEnroe Nadal has made 2 WTF Finals @O2 I attended the one in 2010 against Federer. @Wimbledon follows the computer rankings in 2021. This isn't new news!

  • rspick85 Rory ***** (@rspick85) reported

    @CorbyGoonerII @O2 Nasa can send photos millions of miles apparently but we can't get signal indoors?

  • laisoliveirabrs Lahhhhhh (@laisoliveirabrs) reported

    @O2 @cafeyn_uk CAFEYN IS AN EXTREMELY RUBBISH SERVICE. I ONLY GOT TO KNOW THIS BECAUSE IT WAS AN O2 ADD ON. WHEN I CLICKED THE LINK SENT BY O2 IT MADE ME LINK IT TO MY PAYPAL. CAFEYN CHARGED ME FOR A FREE SERVICE SINCE DAY 1 AND DOESNT WANT TO GIVE MY MONEY BACK

  • bri66thomp Bri Thompson (@bri66thomp) reported

    @karleburford @O2 Hence why I left @O2 To be in a major city and have no signal or internet connection is ridiculous, and they should give everyone their money back, for not being truthfull about their network.

  • Sammiebutler88 Samantha Bull (@Sammiebutler88) reported

    @O2 So @O2 I'm starting to wonder why i pay my phone bill when still signal is appalling. You tell me to use WiFi calling instead of fixing network issues. What happens when I'm somewhere that doesn't have Wifi such as when I'm at my grandmothers house and may need to call family?

  • LilacNannie LilacNannie (@LilacNannie) reported

    @O2 @tescomobile sick of having intermittent signal. Hours of no signal despite assurances there isn’t a problem. THERE IS!

  • RyanC__24 Ryan Clegg (@RyanC__24) reported

    @O2 Hi O2 I have followed your instruction and yet still have bad signal where I love and travel in South West. I mean come on reputable company like your self providing very poor service in which you state you have good service barely get 4g let alone 5g #badservice

  • kimmi_93 Kim (@kimmi_93) reported

    @O2 Since I’ve had a text saying your turning my 4G off my phone isn’t working probably and going really slow. I don’t pay £70 for nothing

  • natashakearns_ 𝐍𝐀𝐓𝐀𝐒𝐇𝐀 (@natashakearns_) reported

    Erm @O2 can you please tell me why I just came through to someone else’s phone call with an adviser? I’ve just heard their whole name and conversation.. I put the phone down the second I realised it was another customer.. not really professional surely!! 🤨😳🤯
