  • 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!

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • 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 St Albans, England

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

  • 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. 👌👌👌

  • 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

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

    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

    @sabbia1968 @O2 I know when 5G 1st came to my area, the infrastructure was still being worked on. This would cause it to slow down. Now that the area has full coverage it's fine.

  • katerolfe Kate (@katerolfe) reported

    @O2 what’s wrong with your signal? No 4G. Multiple locations. Why am I paying for a service I’m not receiving ???

  • lucytmeredith Lucy Meredith (@lucytmeredith) reported

    @O2 @Ian57586675 Hi @o2 I have the same 4G issue in Harrogate as does everyone else I know on O2 here. It’s been like this for years. Usually in town centre can only get very slow 3G. I’ve messaged you several times about it, always get the same reply about the mast issue. Will it ever be fixed?

  • xxsteph_89xx Stephanie Hunter (@xxsteph_89xx) reported

    @O2 been trying to get through to someone on 202 and keep getting hung up on.I want to talk about my recently placed upgrade. Order was meant to be ready yesterday and been told there is an issue with it but cant get through to anyone. Now tried 5 times and hung up on each time😡

  • David_b21 David King (@David_b21) reported
