  • 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 ...

  • 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!

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • 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.

  • 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.

  • 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?

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

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

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

    @O2 dm pls. I have a problem

  • 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.

  • 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!

  • 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!

  • 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..!

  • 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

  • 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.

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

    Poor network in Se6 @O2

  • 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

  • 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?

  • 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?

    @Kymberley__M @LHarrisSwann @O2 Had the same issue, honestly so annoying.

  • ryanstanley22 Ryan Anderson (@ryanstanley22) reported

    @O2 I’ve already done that, it’s showing no issues and apparently it’s been fixed

  • capnmac85 capnmac 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦 (@capnmac85) reported

    @O2 I have now with the help of the nice people at the o2 shop worked out there is a fault with the phone. This phone was given to me in February by @O2 insure. They are refusing to fix it without me paying an excess. I did not cause this problem. The phone was faulty.

  • pawseygirl Louisa ⭐️⭐️💙💙🏆 (@pawseygirl) reported

    @O2 are you having an issue? My 5G has suddenly stopped working

  • katieFHQ Katie Ann Grime (@katieFHQ) reported

    @O2 you call me off 0800 840 0202 to ask me how my complaint call went, when I say I want a discount because you can’t give me signal YOU cut ME off. You could of called me back as you called me in the first place #Shockingcustomerservice

  • GD201201 DG (@GD201201) reported

    @O2 nearly a week now and a mast near home still isn’t working so no calls or data. I wonder if the rest of your customers know that you don’t guarantee service but still expect payment. Surely we’re paying for a service and once you stop providing said service, we stop paying?

  • salsasquad SALSA SQUAD Cheltenham (@salsasquad) reported

    @o2 terrible experience since switching over from Plusnet to 02. Four weeks without being able to receive business calls. 3 promises by 02 tec support it will be fixed within 4 hours. Nothing. Turns out it’s a split port issue but I had to find that out from Plusnet tec support!

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 I have a quick question can O2 disconnect an customer’s contract without their permission?

  • katieFHQ Katie Ann Grime (@katieFHQ) reported

    @O2 rather than selling your phones, contract and network to new people that you can’t provide signal too, try and focus on your existing customers and swamped masts #Ofcom #Consumerrights stop taking our money if you can’t provide a service #theft

  • FPLJazz01 FPL Jazz (@FPLJazz01) reported

    @Irons_FPL @AnthonyUsher @O2 It’s been 7 days for me! Still no luck and cut off from previous provider. Can’t so much as make a call or receive a call. I’ve dropped off the planet. Was told it’s possible I’ll lose my no for good! 😡 Temp number doesn’t work either, no network. Absolute joke!
