    @ThreeUK shocking customer service, after being a victim of assault and phone being withheld for evidence was not offered a temporary replacement.

  • ChallengeLewis Lewis' Challenge (@ChallengeLewis) reported

    @ThreeUKSupport Said I owed money and that I cancelled my DD (I haven’t) wanted to confirm my bank details. They had my 3 number (was a 4g wifi) email and postcode. Guessing that 3 has shared my info with someone else?!?! Or a data breach? I was only a customer for 2 weeks!

    @ThreeUKSupport I'm trying to top up a SIM that has run out of data and it's saying the app and website are down. It has been like this all day. Any idea when it'll be fixed?

    Hey @ThreeUK I need some help

  • mullers72 Phil Mullin (@mullers72) reported from Welwyn Garden City, England

    So having just bought a @ThreeUKSupport PAYG SIM for my son as he's lost his phone, I can't register it online as it's down for technical maintenance but call the 0800 number. That's closed too. How do I get him sorted for school tomorrow? #Threeuk

  • DonWillian1_ Mempis (@DonWillian1_) reported

    @ThreeUKSupport my 4G is not working, can you help me out?

  • _Suzieee_ Suzie Wallace (@_Suzieee_) reported

    @ThreeUKSupport I was assured by one member of customer service yesterday that it would definitely be done today and she would phone me by 3pm today to confirm. I never heard back. I chose to stick with 3 instead of moving to another PAYG network, but I’m starting to regret this decision!

  • gabyFormica Gigi♥ (@gabyFormica) reported

    @ThreeUK also your customer service very poor especially Anna

  • 1Jonesey ReeJones (@1Jonesey) reported

    @ThreeUK I've suffered network issues all week and as a result struggled to make phone calls. I'm still struggling to make calls and have been told network issues will be ongoing till 17 March. It's mother's Day, and I've not been able to speak to my mum. Not very happy three!
