  • 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.

  • 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

  • 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.

  • 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!

  • 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.

  • 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 ...

  • 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?

  • 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.

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

    Poor network in Se6 @O2

  • 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?

  • 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

  • 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.

  • 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!

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

    @O2 dm pls. I have a problem

  • 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..!

  • djmhenry Dave Henry (@djmhenry) reported

    @O2 somehow you've made your customer service even worse! I'm stuck in new zealand with a locked phone and a code that doesn't work. And your customer service keep giving me half answers, and then saying I need to recontact you during work hours!

  • Inthemanshed Stu (@Inthemanshed) reported from Macclesfield, England

    @O2 send me a link to DM you please. I’ve spoken to a o2 employee but still have no network!

  • abridge__ A Bridge to Tranquility (@abridge__) reported

    Twitter Rant @O2 Me "I've been having signal issues at my home address & within 3 miles meaning unless I use WiFi, I have already contacted you about this issue" @O2 "sorry, have you tried changing etc.." Me " yes I've already have attempted these as stated above" (1/2)

  • clare_jeffs Clare (@clare_jeffs) reported

    @O2 @Apple my phone says no caller id when anyone rings me. It sometimes resolves with. Reboot. I’ve tried network settings, software updated and factory reset. Any ideas?!

  • NicolaMaddox6 Nicola Maddox (@NicolaMaddox6) reported

    @O2 so here I am, a week later, no sign of my refund, no sign that I’ll ever be able to speak to anyone who might be able to help.

  • isaac_t_6 Isaac Thompson (@isaac_t_6) reported

    @djmhenry @O2 They give users a lot of runaround on issues like this, you can message “syncunlocks” on instagram to get it unlocked, they helped me out with mine

  • bluegaschris chris fear (@bluegaschris) reported

    @O2 Great greggs but never no signal I hate o2

    @O2 Another day of no service. Despite promises it would be back.

  • MyriadPhoto MyriadPhoto 📷 (@MyriadPhoto) reported

    I sent a DM, explained, asked for CEO contact details then no response. @O2 thanks for no help again.

  • WRNicholls Will Nicholls (@WRNicholls) reported

    @O2 I will be - I haven’t yet. I moved to O2. My number ported in and worked. 3 hours later service died and never resumed. Port team said they’d fix it and they haven’t. So I still have no service with O2. I’ll be giving my PAC back to EE on Monday to send the number back 1/2
