  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    @ThreeUKSupport Worst company i’vr ever encountered

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    @ThreeUKSupport Worst company i’ve ever encountered. No wonder why your basically failing as a company

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Yes I usually switch between when my 4G struggles. My calls have been dropping and not working properly too though in a variety of locations.

  • thisisjmx James Vincent 🏳️‍🌈🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Cardiff, Wales

    @ThreeUKSupport Yeah there weren't any issues. Just no inside signal. There was definitely no 3G & no VoLTE either. Just thought I'd mention it. Mayb a consideration for future network upgrades.

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Have been with @ThreeUK for years and always been very happy with service. However since renewing to a 24 month contract and 5G getting turned on, my service has been absolutely terrible. Terrible or no 3G/4G, calls cutting out or failing. 1/2

  • TheMMEvent Mike Anthony Moreno (@TheMMEvent) reported from Cardiff, Wales

    Another day where @ThreeUK fails to provide decent phone service. I’ve got full signal but yet my services is so slow. #whatamipayingfor

  • richieh Richie H  (@richieh) reported from Caerphilly, Wales

    @ThreeUK @ThreeUKSupport Haven't had any service at all since yesterday and still nothing, with a business to run.....

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    On hold to @ThreeUK possibly the worst phone company i’ve ever encountered in my whole life

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DanielIqbal1999 @ThreeUK That should not happen. If the Three signal fails a 999 call should automatically be routed through any alternative network .

  • Dariogutier Darío Gutier (@Dariogutier) reported from Cardiff, Wales

    @ThreeUKSupport Is the same whit whatever I do. Every area I’m going specially when is crowded around me. I have changed SIM cards, phone and the problem is still here

  • AnnaB_Cdf Anna Brzezinska (@AnnaB_Cdf) reported from Cardiff, Wales

    Just came back from North Wales and thanks god I have a sat nav & sos button in my @MercedesBenz as otherwise my journey in the morning would involve searching for an actual road map since @ThreeUK was down, so no service nor data during 4h journey from Cardiff 👎😑🙄 #threedown

  • Dariogutier Darío Gutier (@Dariogutier) reported from Cardiff, Wales

    @ThreeUKSupport Yeah and the problem was still there, my phone was changed because apparently was the phone and the problem is still here! It’s been 2 years contract in hell!! I can’t wait to finish it

  • Mrs_Thomas82 Sarah Thomas 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Mrs_Thomas82) reported from Maesycwmmer, Wales

    @ThreeUK My service has been fine. My husbands on the other hand has been non-existent since last night.

  • mindspits Rhys (@mindspits) reported from Cardiff, Wales

    @mythofechelon @TMobile Could be a @ThreeUK issue as their network was down overnight.

  • elisemarylin éli (@elisemarylin) reported from Barry, Wales

    @ThreeUK i literally need my phone to study yet i can't because your phone lines are down, absolutely ridiculous. i will 100% be switching after this, thank God my contract is up.

  • alunT Alun Thomas (@alunT) reported from Caerphilly, Wales

    @ThreeUK network down after I ios update overnight #threedown

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RIKZ200 @EE @jay_smithy_13 @ThreeUK I couldn't agree more. 3's coverage is the worst of them all. Duped by their lying 'coverage' map. Can't even get a signal in my house. Roll on moving back to #EE

  • thisisjmx James Vincent 🏳️‍🌈🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Cardiff, Wales

    So 2 weeks ago there was a 4G issue in my village with speeds in kbps range. It's been better but last few days now fine 50-70 Down, around 18 Up. @ThreeUKSupport It's not easy when living a completely mobile network operator life. No home fixed ISP. 1/2

  • MisCatD Cat 🖤 (@MisCatD) reported from Cardiff, Wales

    @ThreeUK customer service is horrendous

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DJAshBash @ThreeUKSupport I'm a Three user and have had experience of both good and bad network in and around the Cardiff area. What Three are stating is true but it's taking longer than they planned originally. Three have the largest 5G bandwidth allocation of all the UK networks plus they also have..

  • DanieleMessina Daniele Messina (@DanieleMessina) reported

    @ThreeUKSupport The postcode is S20 5ER. I told you multiple times. Your guys said the issue would be solved by 7th Feb. Nothing happened. One guy even wanted to waste my time troubleshoting my 5G hub, which is obviously fine.

  • HDv2b Hussein Duvigneau (@HDv2b) reported

    @ThreeUK I've called them out on this before, and here we are a few years later and nothing changed. I say this having had my @ThreeUK account hacked into in the past, from here they were then able to intercept SMS 2FA into my bank accounts and empty them. I don't take this issue lightly.

  • GillyWrenn Gill Wrenn (@GillyWrenn) reported

    @ThreeUKSupport Thank you. It seems to be ok now, but phone didn't work very well during that time. Believe there was a fault but had to search for that because it wasn't on the 3 app. Not very good service on there lately. Contract up shortly and we are seriously considering coming away from 3!

  • sakibmshaikh Sakib (@sakibmshaikh) reported

    Hey @ThreeUK, it's been 15 days since my broadband 5G stopped wrking and was promised a fix by today, but nw told it's delayed till March 2nd. Not happy with the rude customer service either.Can you pl provide an update and bttr service 4 ur paying customers? #CustomerServiceFail

  • JamesGa34740199 James Gallimore (@JamesGa34740199) reported

    @ThreeUKSupport rang in to speak about my upgrade. Spoke to someone who refused to help me, refused to call me back and claimed the systems were down - clearly this is because he wanted to go home as called straight back and it was closed. Embarrassing

  • RalphNe32269576 Ralph Nelson (@RalphNe32269576) reported

    @ThreeUK Your @ThreeUKSupport hasn't been touched since 2021. Your Three UK online chat service is not working AGAIN. Perhaps this explains why your internet speed is s*** again.

  • DanieleMessina Daniele Messina (@DanieleMessina) reported

    SCAM. IF YOU ARE IN SHEFFIELD, DON'T GET A @ThreeUK HUB. THEIR NETWORK DOESN'T WORK AND THEY'LL TAKE YOUR MONEY AND WASTE YOUR TIME.

  • SteveEditor Steve O'Gorman (@SteveEditor) reported

    This month's award for Worst Customer Service is going to be too close to call, with so many strong contenders in the field. I think it'll be a photo finish between @StagecoachWales and @ThreeUK. All to play for in the next three days. Watch this space ...

  • benecios Benecios (@benecios) reported

    @ThreeUK Absolutely shambolic service, 2 accounts fradulently opened in my name, after 1hr 40mins of phonecalls and live chats I am none the wiser. Really really poor. I would have thought something as serious as this would not be dealt with by an Indian call centre.

  • markjdow Mark Dow (@markjdow) reported

    @ThreeUKSupport trying to top up pay and go as it’s months since I used the sun for mobile broadband. Enter number and email and when it hit password reminder tells me the system is down saying there is tech issues
