    @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..!

  • 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?

  • 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.

  • 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.

  • 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?

  • 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

  • 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.

  • 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

  • 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!

  • 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.

  • 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

  • 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.

  • 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!

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

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

  • 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 ...

  • 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

  • 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.

  • Ellie_May7 Ellie (@Ellie_May7) reported

    @O2 hi there! Im in France with my uk phone and I can’t use my data, even though I have my roaming on. I also can’t hotspot from another o2 phone. Please help!

  • clarencewalk David Smith (@clarencewalk) reported

    @O2 how do i contact your customer service - cant find any number on your website

  • martinwwhite72 Martin White (@martinwwhite72) reported

    And! While this failure to provide the basic service that consumers are paying for continues, companies like @O2 keep charging full price as though there was nothing wrong at all

  • Manta1970 SammTimms (@Manta1970) reported

    @O2 I want to keep my current tariff but your website just takes me round in circles and I don’t have time to wait a half hour to talk to someone. Can someone help me with my simple request ?

  • bennmarkpotter Benn Mark Potter (@bennmarkpotter) reported

    I’m with @O2 (who you’ve merged with) and I’m never leaving them.

  • kangaruth Ruth Davidson (@kangaruth) reported

    @O2 you have overcharged me for my #DisneyPlus extra this month and I can't get through to anyone for help.

  • Ellie_May7 Ellie (@Ellie_May7) reported

    @O2 Sorry what do you mean by manually selecting another network? I’ve put my data on but it doesn’t work 😕

  • brandiclayton24 Brandi Clayton (@brandiclayton24) reported

    @O2 my phone shows full signal and data is working but cannot make or receive calls - doesn’t even connect. Been down for hours now.

  • AliJLab Ali L (@AliJLab) reported

    @O2 Thanks - I know why it is, it’s because half the country is on holiday here and the network can’t cope with the number of people trying to connect. Any chance something might be done about it so I can actually use my phone next summer?

  • chrismoor Chris Moorhouse (@chrismoor) reported

    @O2 been having problems all day in Richmond upon Thames. No service and no WiFi calling either. Real problem for me as recent transplant patient. If hospital can’t call me it’s a big issue!
