  • cubious Hornbeam (@cubious) reported

    @ThreeUKSupport Hello, I just bought a 4g router from you and speed tests are showing 20Mb download speed but Giffgaff are providing 40Mb at the same location. Do you just have a slow network?

  • cycleoptic cycleoptic💙💚 (@cycleoptic) reported

    @ThreeUKSupport as i explained that only covers the 5G signal, not the internet contained within it ! it *always* shows “ no problem” when the internet speed is very low or zero. unacceptable upload speeds are presently only 3% of the ( acceptable ) download speed in N19 4RN

  • tvdrbarb tvdrbarb*fullyvaxxed (@tvdrbarb) reported

    Despite my proof in writing that this was agreed and supposedly processed, they not only did not process, but want to charge me 47£ more AND when I said then I'd leave, stated they'd charge me £53 if I left today... @ThreeUK may be the worst when it comes to fixing their mistakes

  • LFCDaniel17 Dan (@LFCDaniel17) reported

    @ThreeUKSupport my internet is being very slow to not working at all anything you can help with?

  • jordanbishop11 Jordan Bishop (@jordanbishop11) reported

    Great switch to @ThreeUK effortless with great support. Sorry @EE had to make the move no rewards for loyal customers, couldn’t match the deal I had with 3. 17 years I’ve been with you time to move on.

  • siannyb26 Sian Brown (@siannyb26) reported

    @ThreeUK your customer service is totally appalling and beyond inflexible. I have a vulnerable 22 year old female that can’t use a contract we are paying for because of your bad advice

  • siannyb26 Sian Brown (@siannyb26) reported

    @ThreeUKSupport But bad advice is not acceptable. this could have been avoided if we had the right advice in the first place. As a minimum you should commit to providing my daughter with free top up on the pay as to sim which she now has to use until we can get the right sim to her

  • picklespick Tracy Pick ⚫️⚪️🇦🇺 🇬🇧 🇫🇷 💙 (@picklespick) reported

    @ThreeUKSupport Well I have tried that explained the situation….wants to talk about my phone contract! NO I need to know about network issues! Still no answer!

  • picklespick Tracy Pick ⚫️⚪️🇦🇺 🇬🇧 🇫🇷 💙 (@picklespick) reported

    @ThreeUKSupport Yes you sent that yesterday too! All I want to know is when the issue in HU8 9 will be resolved

  • haddington Me (@haddington) reported

    @ThreeUKSupport Hi Jenn. Yes been on the live chat. Been through all the usual. You sent me a new sim as well which has made no difference. Like I said, this isn’t an issue with me as all other people on 3 are having the same issues all over Sheffield. 3G fine, 5G fine. 4G not.
