  • 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 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?

  • 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.

  • 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.

  • 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!

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

    @O2 dm pls. I have a problem

  • 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

  • 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!

  • 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

  • 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

  • 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

  • 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?

  • 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.

  • 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

  • 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..!

  • 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.

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

  • 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.

  • 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 ...

  • chelsea_woodss Chelsea Woods (@chelsea_woodss) reported

    Honestly think 02 has the worst customer service team I’ve ever dealt with. Trying to deal with such a small issue over the phone turns into a 2 hour call getting passed around to over 12 people….and then they hang up!! Lord give me strength, glad I’m changing over @o2 @TheO2

  • bu88yth33lf Paul (@bu88yth33lf) reported

    @O2 not bad - prices increasing and customer service deteriorating - a 45 minute wait is too long.

  • Kayoprice3 Kayoprice (@Kayoprice3) reported

    @O2 After all, my phone never been connected to mobile network in Spain. It was a terrible experience. What is the reason do you think? I don’t want the same thing happen again!

  • MarysiaT Marysia Trembecka (@MarysiaT) reported

    @O2 2/2 Vodafone are saying they cant access it as port is done in full, no issues their end. o2 are saying they waiting on vodafone - they emailed 16/2 - I am stuck in the middle now with no text msgs for 4 days.. and no way to verify bank statements, chrome and apps such as uber.

  • jdmusicdevon jdmusicdevon (@jdmusicdevon) reported

    @O2 It is poor. Time and time again.

  • KatyKimberley Katy (@KatyKimberley) reported

    @O2 hi there, my brother is in Santiago, Chile and his phone has been stolen, I need to cancel his sim some how, any idea how we can do this? He had to borrow a strangers phone to tell me. Any help would be appreciated please? Thank you

  • ChallengeKanza Kanza (@ChallengeKanza) reported

    Awww the poor CEO of @O2 just wasn't earning enough money that's why the company is going to screw customers for inflation busting rises in our bills. Utterly disgusting during a cost of living crisis with no evidence of why such an increase is needed. Ppl will remember this!

  • ohbettyno 𝙱𝚎𝚝𝚑 𝙲𝚘𝚠𝚎𝚕𝚕 (@ohbettyno) reported

    @O2 I’m looking to port my old number over to my new o2 sim, I have my pac code but can’t find an online form to enter it, any help?

  • JamesRoberts330 James Roberts (@JamesRoberts330) reported

    Hey @O2 how long is it normally between a new mast being erected and it being turned on and active? There’s a new mast gone up by my house (after Feb 2022) showing that it’s 5G but there’s no 5G in my area on the coverage map so it’s still not working yet. Thanks. James #O2 #O2UK
