  • 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

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • 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

  • 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!

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • 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

  • 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. 👌👌👌

  • 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

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • 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

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • 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.

  • johndpmc none of your business (@johndpmc) reported from Luton, England

  • mohcader Mo Cader (@mohcader) reported

    Worse thing is your customer service staff who has a I don’t care attitude working from home said to me just sign up as a new customer and get your pac code when I am already a @O2 customer! No logic at all!

  • Tigercrawl helen 💙 (@Tigercrawl) reported

    @O2 Wow ! So today I had to return a faulty iPhone 15 purchased last day of November 21 and Young daughter will be without phone for a whole week minimum ! How is this service ?? You don’t offer a loaned model what about her safety and safeguarding ?DO BETTER !

  • NathFerguson Nath (@NathFerguson) reported

    @Katy_mo @O2 Exactly my 4G and 5G has **** been like it for over a year and they don’t care about fixing it all they want is ur Money year after year they increase your bill but the service doesn’t improve the more you complain the more they ignore you just refuse to pay it till they fix it

  • wouldanyonecare Jacob Tyler (@wouldanyonecare) reported

    @O2 I never got a text or email. I’ve checked. And okay great, I’ll check previous bills from my laptop to see what this odd charge is. Thanks

  • kaffachino kat (@kaffachino) reported

    @O2 I’ve had my device just over a year and the battery life has declined very quickly. It barely lasts half the day despite me barely using it during the day due to lack of service and the fact I work 8-6.. is there anything that can be done?

  • HM5182 Hayley Stevenson (@HM5182) reported

    @O2 is there an issue with online chat? My contracts merged on Friday and I cannot use the conversation with an assistant since but need help with my bill

    Cancelling my @o2 contract. Worst coverage I’ve ever known from anyone

  • Mk3laserboy Simon (@Mk3laserboy) reported

    @O2 have a serious issue with you.... I'm moving across from another provider Monday. Your rep on the phone says to turn off my phone when current provider goes out of service, then wait and reboot phone, yet YOUR text message says turn it off all day?? Can't do that..explain...

  • philhellena dame philhellena (@philhellena) reported

    @O2 Still regularly getting No Signal due to a fire at a local mast WEEKS ago. And now you have the cheek to tell me you’re putting up prices!

  • Hellywelly19 Hellywelly (@Hellywelly19) reported
