  • JasSinghBrar Jastalavista (@JasSinghBrar) reported

    @ThreeUKSupport I’ve never even received a confirmation email of the order, or a text confirmation. Honestly, disgusted is an understatement when I’ve taken days off work because of this

  • stevedouglas76 Steve Douglas 🇪🇺 🇬🇧 (@stevedouglas76) reported

    @ThreeUK Why can't I disable the automated text telling me I've got a bill? Texts are terrible for this, I can't filter them and I'm not particularly interested in checking my bill as a matter of urgency

  • LFCSovereign61 Paul 🔱#Sovereign 🇬🇧 (@LFCSovereign61) reported

    @ThreeUKSupport And I’m still having trouble connecting to the App as I keep getting the message that the number is unrecognised.

  • GraceCRoberts Dr Grace C Roberts 😷🎄 (@GraceCRoberts) reported

    @coedwiggle @ThreeUK Currently just 🤞 for functional! (I feel so bad getting a new one cos it isn't very green at all!)

  • Rabmcd1 Rabmcd (@Rabmcd1) reported

    @elainecarey3 @ThreeUK @ThreeUKSupport It continues, Still refusing to supply a sim card while billing me for the pleasure. DO NOT USE "THREE" Go to any other company. Terrible broken english live chats and refuse to help.

  • Atomicstrength Atomic strength (@Atomicstrength) reported

    @ThreeUK what a con. Why is it today that I have bought a phone from you, and told I HAD to pay £10 for a PAYG SIM pack, and couldn't refuse it as part of the phone sale? What a waste. Nice to be a valued return customer!

  • FlappyBerk King (DeDeDe) (@FlappyBerk) reported

    @ThreeUKSupport No worries, I appreciate these things take time. Can you try CB7 4NT (nearby postcode with the same issue) please? I'm fine waiting, but if there's a rough ETA on your system I'll know whether I need to arrange a backup SIM with a different network. Thanks

  • FlappyBerk King (DeDeDe) (@FlappyBerk) reported

    @ThreeUKSupport The webpage says it's a nearby mast that's down so it's congested the working one that covers that postcode, as those who would have connected to the other mast are now connecting to it. The issue now is 4G and 3G are practically unusable.

  • Joe66630174 Joe (@Joe66630174) reported

    @Three_Is_Broken @elainecarey3 @ThreeUK I've just been to Bournemouth town centre to do some Xmas shopping and I was disgusted that there was just 1 bar of signal in Bournemouth square. Typical dreadful service from Three again. As usual!!!

    @ThreeUK speak to customers like absolute rubbish and then put phone down on her
