  • 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?

  • 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.

  • 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

  • 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 ...

  • 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

  • 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

  • Borehamwoodbine Woody (@Borehamwoodbine) reported from Borehamwood, England

    In over 9 years with @O2 I’ve hardly ever needed customer services help and now after 3 attempts this year with little or no help I would just like to say thanks for nothing!

  • 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?

  • 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.

  • lexibeqiri Lexi Beqiri (@lexibeqiri) reported from Barnet, England

    @O2 Bought a pair of airpods in september and I have problems with the right one for over a week. It is not connecting properly. What is to be done? Thanks!

  • 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.

  • 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..!

  • 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?

  • bukachef Fine Chef Damilola🥰 (@bukachef) reported from Harrow Weald, England

    @O2 dm pls. I have a problem

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • 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!

  • 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.

  • 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.

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • gary_lee_gaming Gary's gaming clips 📹🇬🇧😀 (@gary_lee_gaming) reported

    @O2 @hubbubUK I would but my old one is broken do you repair them also?, EG screen replacements?

  • Djfridgetwit Richard Howlett (@Djfridgetwit) reported

    @O2 Can you sort out the signal at #BrandsHatch please. It's shocking at the moment. As in it's a shock when there actually is some

  • PDawson89 Paul Dawson (@PDawson89) reported

    @O2 @hubbubUK Fix your network first the 4g speeds in my area are rubbish on a good day I get 2 mbps we're my family on EE get over 100 can not wait for my contract to be over with o2

  • BearHadley Hadley (@BearHadley) reported

    Having nothing but problems with @O2 at the moment. Their signal coverage seems to have considerably dropped and I’m struggling to get any speeds even when on 4 bars of 4G. Any recommendations for alternative providers is welcomed

  • BearHadley Hadley (@BearHadley) reported

    @O2 And I appreciate I only have 2 bars of 4G but for the response test to fail and not even run is a little concerning.

  • LilacDixie Dixie (@LilacDixie) reported

    @O2 Yes there's a problem! Have little or no service at home! Thank god for wifi calling or i wouldn't be able to make any calls. When i do have 3 or 4 bars can't connect to the internet!

  • CK_Chainz R (@CK_Chainz) reported

    @virginmedia @O2 **** your ****** company I’m payin money for jack **** internet quality. Worst company in the world, somehow worse than EA hope ur ****** company goes bankrupt

  • accessstratford Accessible Stratford (@accessstratford) reported

    @O2 for weeks due to a network problem a phone mast not working properly, CV37 7 HG, you update me weekly, sometimes more often but a repair would be preferable. Yesterday you said ‘services might be affected’ but today have said ‘services won’t be affected’. Which is it?
