  • 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

  • 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

  • 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.

  • 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

  • cove123 mark nicolson (@cove123) reported from Welwyn Garden City, England

  • 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

  • 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

  • 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!

  • 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

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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

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

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

  • 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

  • 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 👏.

  • AndreaFisher5 Andrea Fisher (@AndreaFisher5) reported

    @O2 Every single time I'm here, it doesn't work. I'm paying money each month for something not to work. Each & every time I Tweet about your terrible service, you always say Sorry. Sorry is NOT GOOD enough. Looks like I'll have to cancel & tell my friends too

  • dlvc1981 donna cox (@dlvc1981) reported

    @O2 shocking cus service!Ring and on hold for about 30 min to be cut off, same on 2nd call. Finally got through, told I needed connections team,she agreed I was entitled to refund the line went dead.... where is my call back o2? Its not like you don't have my number. Call me!

  • pompeyhedge ed francis (@pompeyhedge) reported

    @mrbio1984 @VodafoneUK @O2 Stick with three. I'm lucky to get 1mbps with useless Vodafone. Absolute joke. Also no WiFi on the underground and roaming charges. Never using them again.

  • JillLBarnett Jill Barnett (@JillLBarnett) reported

    Is @O2 down in Edinburgh? Had no service for hours

  • fire3090 Lisa w (@fire3090) reported

    @O2 Nope I didn't because I didn't want to A hang on the phone for 40 minutes and B go through it all over again. I await a response from my email

  • howardgunn Howard (@howardgunn) reported

    Such a shame that @EE retention offers are so breathtakingly poor. Looks like after 20+ years i'll be moving to @O2 as their offers are pretty good (£15 per month less than ee on a like for like basis) plus O2 alow roaming in EU without ripping off the customer.

  • Sara_withnoH_ Sara Harris (@Sara_withnoH_) reported

    @O2 can I ask if this number is genuinely calling to discuss my husbands contract 01212840647 & many, many similar numbers to this…ending in 0642, 0638 & 0965. If so the call handlers are incredibly rude & I would request they remove us from the database

  • mrbio1984 MaX (@mrbio1984) reported

    @pompeyhedge @VodafoneUK @O2 Seems bad all over

  • deborahacton Deborah Acton (@deborahacton) reported

    @O2 Good morning. Got a new phone over a week ago now and I’m still waiting for my old number to be transferred. Can you help?

  • stevensm2000 mark (@stevensm2000) reported

    @O2 why is it so difficult to contact you on the phone as I want to cancel my contract.
