  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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!

  • 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.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @EE following up on the bad signal in the area I now stay in, can’t even have a call while walking in the neighbourhood, I may have to make a drastic decision and move to @O2 I’m in a 12 month contract so what are the cancellation terms if you can not provide a reliable service?

  • 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?

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

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Thanks guys. Going to get someone I know with O2 to come through so I can check what your network coverage is like. Wife’s with @VodafoneUK and has no issues.

  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • AlisonBurnsy Alison Burns 💃🏻💋 (@AlisonBurnsy) reported from Borehamwood, England

    @O2 I really need to speak to someone urgently im@trying to pay@my bill and it’s saying zero balance but I can’t call use my internet or text I need my phone and I can’t get through to anyone to sort it pls message me to help£

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • itsnadine_ abena (@itsnadine_) reported from Harrow Weald, England

    @O2 I changed my tariff now I can’t add a bolt on, if I can’t listen to this mix whilst on a run I’ll cry help

  • 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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • 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.

  • 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..!

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Tottenham, England

    @O2 You have had this problem for the last 20 years doubt a self help guide will work. Ive made several complaints so end of contract I will be looking for a new service provider ...

  • 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?

  • Miss_luton Kirsty Louise (@Miss_luton) reported

    @O2 why is your 4G and 5G data services so poor? I can never access data in busy areas such as Luton town centre, several parts of St Albans and often when in London. What are O2 doing to improve network capacity?

  • EledaEdwin Adele Edwin-Lamerton (@EledaEdwin) reported

    @O2 I've sent a DM asking for support. Could you please respond?

  • MVP_129 #JoshHocken (@MVP_129) reported

    @O2 Been locked out of my account and customer service cant get me back in. On hold for hours last 2 days and no further forward! Im trying to upgrade my phone and see my options.

  • MarkAntonyOwen Mark Antony Owen (@MarkAntonyOwen) reported

    Dear @O2, I need help. I drove to Guildford earlier this evening, and on arrival, my network signal vanished. I couldn't make calls nor use mobile internet. Every setting on my phone says I'm registered on your network. But the second I leave a Wi-Fi connection, nada. What gives?

  • GXuru5 G.X.uru (@GXuru5) reported

    I was Quick enough to go off on one with @O2 when I had an issue but it is fixed TOOK like 2 months though but is fixed the first 2 guys I spoke to useless the girl who took the last call she was very PROFESSIONAL and did her job FULLY so thanks I guess

  • HayleyJ87 H 🦢🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@HayleyJ87) reported

    Is @O2 down? I know it’s rare to get a signal anyway but no network at all tonight in Swansea

  • AndreaSears65 Andrea Sears (@AndreaSears65) reported

    @O2 my Toby voucher has expired before I’ve used it. Help?

  • KieranLeeDoyle Kieran Doyle (@KieranLeeDoyle) reported

    @ProPhotographyP @O2 Don’t Join O2…. I’ve just made the mistake and they are the worst for Customer Service and network signal…. Would have more luck sending smoke signals

  • FrannPG Frann Preston-Gannon (@FrannPG) reported

    I had a very convincing call from someone pretending to be from @O2 offering me 40% off my next bill due to bad service in the last month. They then said I should be receiving a code via text to prove it was legit. Luckily I didn’t give it to them. Watch out for this scam!

  • OliviaMitche Olivia. (@OliviaMitche) reported

    @O2 hi, I’ve received a bill for using my phone in Albania but I’ve never been to Albania 🙄
