  • 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!

  • 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

  • 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

  • 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

  • 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.

  • 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

  • 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

  • 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 👏.

  • 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

  • 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.

  • 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

  • rory_livi Rory Leiper 🚵 (@rory_livi) reported

    @O2 It says ‘your number is not permitted to use this service’ but I’ve used it in the UAE previously. I didn’t reset the PIN as I assumed it would still work.

  • mickirook Mick 'n' Patch (@mickirook) reported

    @O2 I've had the same problem with EE, Vodafone and 3. They managed to sort the problem out within 4 hours. Three weeks later and you lot are still sending me demanding letters. Says a lot for your customer services. USELESS.

  • graystonnixon Grayston Nixon (@graystonnixon) reported

    @O2 Hi, I’ve just wasted 40 mins of my life calling customer service. Inaudible communication, 3 transfers, mind numbing music and call just terminated. Such a simple request - how to connect my new 02 phone to my existing 02 Boostbox.

  • combat_boot 𝗖𝗼𝗺𝗯𝗮𝘁 𝗕𝗼𝗼𝘁 (@combat_boot) reported

    @O2 I ask to be put through to security/anti-scam team. They put me on hold for 20 mins & then hang up.

  • gffcontwitch OFFICIAL GFFCONTWITCH 🇬🇧 Full Force Clan (@gffcontwitch) reported

    @O2 That link is to check if I am connected to the network, but I am connected, I'm just have text in issues

  • combat_boot 𝗖𝗼𝗺𝗯𝗮𝘁 𝗕𝗼𝗼𝘁 (@combat_boot) reported

    @O2 Meanwhile their scammy mates try and get you to help them brake into my account/phone and your security sends me a code. But the scammers do not get code I do.

  • SteelTaylord Andy Taylor (Socially distant since 1987) (@SteelTaylord) reported

    Wish I could afford to buy myself out of my @O2 contract so I can switch to @EE. Constantly doing work in our area but the service gets worse and worse every day. We're at tuw point where I can't make a phone call from my own house. Pathetic.

  • combat_boot 𝗖𝗼𝗺𝗯𝗮𝘁 𝗕𝗼𝗼𝘁 (@combat_boot) reported

    @O2 Your code comes with a warning – “this is bad ju ju, phone us on 202 so we can help”

  • hines_stephen Stephen Hines (@hines_stephen) reported

    @O2 Can you confirm you are also offering help to charities that support male victims? Perhaps one like @StayBrave ?

  • SexyAwesomeMeo1 Sexy Awesome Meow Meow (@SexyAwesomeMeo1) reported

    @O2 I meant to press the Sunday cinema ticket button but accidentally picked Monday how can I fix this
