  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • 1011FOXEE beverley fox (@1011FOXEE) reported from Takeley, England

    @O2 I am trying to apply the discount I get for working at Tesco,it won’t let me use my email as used for my daughters account,help!!

  • rfothergill Ricci Fothergill (@rfothergill) reported from Brentwood, England

    @O2 Nothing received. When was it sent? Last message I had from you was an auto responder on 24th July stating that you’d respond to my complaint within 5 days. Have had nothing since.

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • 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...

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @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.

  • JamesSharp87 James Sharp (@JamesSharp87) reported from Witham, England

    Hello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • KJDalby Kate Dalby (@KJDalby) reported from Chelmsford, England

    @O2 urgent my new provider activated the PAC code provided by you. Their sim card does not work because apparently my device is locked with you. I cannot text you to get it unlocked. Please help asap.

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • IanMaxy94 Ian Maxwell (@IanMaxy94) reported from Billericay, England

    Is transferring of SIM cards supposed to give me no service on both my old and new phone @O2??

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • Kimbles_23 Kimberley Anne (@Kimbles_23) reported

    @O2 Hi, basically I’ve signed up to a cash back app that transfers money I’ve made over to my phone bill provider (you). Apparently I need my customer reference number to determine which of your bank accounts to pay. If you can advise that would be great. Thanks in advance!

  • navdntk Navdeep (@navdntk) reported

    @O2 how can you charge me when you never sent me a SIM card and then after 2 weeks of waiting time, trying to offer me refund half money. How can you charge me when I never received any single service .

  • __Chris22 Chris (@__Chris22) reported

    @O2 Hi, I can't seem to find the info on your site for how to change my wife's name now we're married. Can you help?

  • Pheebs_Clarke Phoebe (@Pheebs_Clarke) reported

    @O2 Hi I’ve been trying to contact someone about increasing my cap as I need to make international calls which is charging me. Going round in circle with automatic answer on phone and can’t speak to an online chat. Can you help, thanks

  • Peter952F1 Peter (@Peter952F1) reported

    @O2 Hi there, hypothetically if I wanted to come to your network and keep my old number, and if I have my PAC code... how do I go about it? Can I just buy a PAYG sim from a shop and proceed that way or what?

  • heyjayandes Jaime (@heyjayandes) reported

    @O2 They have just sent a response saying that the photos supplied clearly show a screen showing blue/pink screen damage, which they do not (as shown in video). Is it also true that there is no complaints procedure apart from emailing the o2 recycling address?

  • nathanaaron12 Nathan Aaron Leonard (@nathanaaron12) reported

    @notorious_twub I’m another @O2 stan!! Been with them years now and wouldn’t go elsewhere! Could never use @ThreeUK after having to go through their awful customer service 🤯

  • cb_x94 xx chloë (@cb_x94) reported

    @O2 I changed my plan last night and now my visual voicemail has disappeared from my iPhone. I’ve lost all the voicemails left by my grandad who recently passed away. Please help!!
