    @ThreeUK Had enough with your service, 13 months of your mistakes, no internet service in my area which I was promised when I joined, £200 in bank charges due to your mistake, hours on the phone with your customer services, worst company I've ever dealt with. #three #fedup #worst

  • ferretd69 Phil Davis (@ferretd69) reported

    @ThreeUKSupport @thegord1 What a load of bollocks. I used to install cell sites and they cover a large area. The last three digits gets the location down to the last 100 metres. They will just tell you to change Sim, reset phone, or that they are working on it.

  • wd_rachel Rachel WD (@wd_rachel) reported

    @ThreeUKSupport I use your 4G broadband in SE8 and have been having massive issues with the internet. It's very hard to get online particularly in the evenings. Is there a number I can call for support? The Three helpline was unable to help with broadband

  • Three_Is_Broken Broken Three UK (@Three_Is_Broken) reported

    @GreenBadgeKOL @ThreeUKSupport They will ask for your full postcode then tell you one or more of these: Congestion To switch to 3G There's work in the area / upgrades SIM problem To restart your phone Fixed in 7 days They've been saying a combination of these things for nearly 2 years!

  • HSkilgannon Vitor (@HSkilgannon) reported

    @ThreeUK I'm trying to buy something on your website. I can't because it does not accept my address even though I'm an existing customer. I call your sales representatives and they want to charge more than the website. What kind of service is this? #Threemobile

  • yousefanani yousef anani (@yousefanani) reported

    @ThreeUK says it has instructed a debt recovery service to pursue me for £20.35. This is despite me never receiving a SIM ftom them after trying to buy a SIM-only deal last year. I have never used their network and they want to charge me? @ThreeUKSupport

  • john13225833 john (@john13225833) reported

    @ThreeUKSupport @ThreeUK I’m outside the UK and my account has been suspended, the support agents tell me that nothing can be done. Is that right? I’m not asking for “free” roaming to be enabled, just be ability to make and receive calls (at international rates). No data needed

  • Mawdrigen Mawdrigen (@Mawdrigen) reported

    I need to get on to @threeuk to correct all the errors with my account as it seems someone entered my d.o.b wrong as when o called them the response was that’s not your date of birth... err I should know

  • AndyB80383770 Andy B (@AndyB80383770) reported

    @ThreeUK Shame you've just imposed such a price hike on your 321 Payg package, you will lose a lot of customers over this, I've been a 3 customer for several years now and will be leaving for another cheaper service provider when New tariff comes into force
