  • abbie_hunt abbie (@abbie_hunt) reported from Cardiff, Wales

    @ThreeUK I had to change my data to ‘3G’ as advised from your in store staff, because the network is so slow atm.

  • reece_evans Reece (@reece_evans) reported from Weston-super-Mare, England

    @ThreeUK why am I paying for a service that NEVER works at my house - BS494EQ

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

    @ThreeUKSupport I’ve just had the worst #customerservice experience I have ever. My knowledge of your products and services was much better than your staff. Also, TV background noise made it hard to understand the Glasgow accent and adviser 2 spoke fast and did not listen 😡

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

    @DJAshBash @ThreeUKSupport @VodafoneUK @ThreeUK I am also on Vodafone. And I would agree they now have overall a formidable network But they have less bandwith 5G than Three..50mHz as opposed to 140mHz so when Three eventually launch 5G 5G it'll be interesting how it all pans out.

  • 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

  • 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

  • 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..

  • SimoneJonesx Simone Jasmine Jones (@SimoneJonesx) reported from Alway, Wales

    Imagine being a @ThreeUK customer with 2 contracts for years on end and being told to find another service provider because they can’t fix the masts in my area and then refuse to refund what I’ve paid off this mobile or even pay my upfront cost for my next phone 😡 #scabs

  • SimoneJonesx Simone Jasmine Jones (@SimoneJonesx) reported from Alway, Wales

    @ThreeUKSupport You have lost me a customer as of today and my complaint is currently with the ombudsman. Your staff and managers are awful!

  • 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

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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

  • 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.

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

    @ThreeUK I have just had the worst customer service experience I have ever had. My knowledge of your products and services was much better than your staff. Also, TV noise un background made it hard to understand the Glaswegian accent and adviser 2 spoke fast and did not listen 😡

  • 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

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

    @ThreeUK customer service is horrendous

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @NathanWyburnArt @Apple I’m having a similar issue and @ThreeUK won’t do anything about it. They told me to download some app which won’t help anyway as it’s unknown caller. I think next step is I’ll be forced to change my number 😐

  • 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

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

    @DJAshBash @ThreeUKSupport ..a new chunk of 4G 1500mHz aka Ban.d 32. When they're actually commissioned the Three network has huge potential to deal with all these issues virtually overnight. Sadly they don't communicate the cause and ther solutions very well hence disappointed customers.

  • Lozula Laurence & Jessica - Finding the Universe (@Lozula) reported

    @ThreeUKSupport hi there, are you able to provide business account support? I've been given a phone number to call which doesn't help because my phone won't connect to a mobile network

  • rowandjack Jack Rowand (@rowandjack) reported

    @ThreeUKSupport Hi. There has been no I ternet connection on my 5g home broadband since 10am today. It is the London SE23 area. What is the problem please?

  • Ianiesta8 Ian Fitzpatrick (@Ianiesta8) reported

    @ThreeUKSupport your signal is rotten in the FK2 7EX area. I got an SMS saying work was being done last week, but now the signal is dreadful.

  • cycleoptic cycleoptic💙💚 (@cycleoptic) reported

    @ThreeUKSupport @hannahloumac it happens all of the time with your internet ( 5G signal good) and you don’t know why ! ( i’ve now been moved to 2nd line support twice, they don’t know either ! )

  • jlcareersuk Jonathan Lewis Career Services (@jlcareersuk) reported

    @ThreeUK @OFCOM Every week for months now I have received a phone call from a company stating they are Carphone Warehouse. I block it the number changes. So has my daughter and now my fiancée who moved to three this month. Never did on O2. How come? Who has leaked this data?

  • KanePurkiss Kane Purkiss (@KanePurkiss) reported

    @ThreeUKSupport I just think it funny that it’s cheaper for me to cancel and leave you then it is to upgrade early makes zero sense

  • alistairclare Alistair Clare (@alistairclare) reported

    @ThreeUKSupport Hi Scott. Yes it’s fine when our of the area - just when walking around our home village where the signal@is good but the internet is unusable. That Speedtest was taken on the village green this evening and shows how slow it is. My wife’s phone has the same issues as well.

  • greenyenergy Green (@greenyenergy) reported

    Hi @ThreeUKSupport I have my replacement SIM now. Put it in but got no service. Do I need to activate it or anything or will it automatically connect after a few hours? Thanks.

  • mejh80081355Arg Max J H (@mejh80081355Arg) reported

    @ThreeUK Your network is utter shite.

  • yusostar yusuf hambolu (@yusostar) reported

    @ThreeUKSupport i received nothing at all, last msg I received was in August, I only noticed the problem when trying to apply for a passport for my newborn and wondered why I had no notifications ...
