  • 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!

  • 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

    @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 😡

  • 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

  • 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.

  • 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.

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

    @PedroClarke1 @ThreeUK Sadly my Three is still crap where I've in Penarth. And it hasn't changed much in the centre of Cardiff either.

  • 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 😐

  • 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.

  • 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.

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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 😡

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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

  • 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..

  • itsmarcie_x - Marcie (@itsmarcie_x) reported

    @AQ74410 @ThreeUKSupport Hello @AQ74410 I’ve just spoken to three who have confirmed there has been a data breach as the issue with the outage caused our called to be diverted to other numbers

  • efwolf359 alan edwards (@efwolf359) reported

    @mikeasharp @ThreeUKSupport @AQ74410 You are the one completely missing the point. It doesn’t have to identify an individual to be a breach. A list of customer account numbers is a breach, a list of customer credit card numbers is a breach, a list of customer telephone numbers is a breach.1/2

  • philrandal Phil Randal (@philrandal) reported

    @ThreeUKSupport She was given the run around until eventually Three resolved the issue.

  • adeola_alabi Adeola Alabi (@adeola_alabi) reported

    @ThreeUKSupport I‘ve been having issues with indoor signal. Spoke with 2 different agents & asked me to switch off & switch on my phone. One also asked me to reset the network settings & will hold on as if d phone will not reboot! I’m fed up with this service & will have to move

  • philrandal Phil Randal (@philrandal) reported

    Once again, my partner isn't receiving OTP SMSs from @santanderuk on the @ThreeUK network. @threeuk tech support are useless

  • efwolf359 alan edwards (@efwolf359) reported

    @mikeasharp @ThreeUKSupport @AQ74410 But the phone number generator doesn’t identify someone as a customer of a particular company. This did. Also a person doesn’t need to be identified for it to be a breach. Email addresses don’t identify an individual person but lists of them have classed as breaches in the past

  • brugmomentem Sussus Amonguss (@brugmomentem) reported

    @ThreeUKSupport getting really terrible 4g speeds of 0.4 MBPS all this week.. compared to two weeks ago was getting 20MBPS+ , what is going on? CF5 area. I am unable to work from home using my iPhone 12's connection.

  • LuSchmoo Lu (@LuSchmoo) reported

    @pheonyxzorro @ThreeUKSupport Hello, sorry to hear somethings happened. However, due to this post having your phone number in, for your account security and privacy, I would recommend removing this post. Not trying to be mean, just trying to help you improve your account security over all.

  • rajprabu Raj (@rajprabu) reported

    @ThreeUK It appears we are having the same issue again today (20th June). Not able to receive calls and make calls. Please can you check on priority?

  • philrandal Phil Randal (@philrandal) reported

    @ThreeUKSupport It was an issue at your end
