  • FrancescaChelC FRANCESCA. (@FrancescaChelC) reported

    I’ve been a @ThreeUK customer for over 13 years. I have never wanted to leave them until they left @ChelseaFC… They don’t know what loyalty is, to the club, staff, players, fans, or even their own customers. I’m moving to @SkyUK they know LOYALTY.

    @ThreeUKSupport Network down CH8 9SA No mobile network no data network no voice network...Tried 3g and 4 4g

  • ChicagoWhite Leeds Fan in Chicago (@ChicagoWhite) reported

    @ThreeUK just signed up for a 4g+ mifi plan in Reading getting either no coverage or abysmal connection speeds < 1meg down & 3meg up never know up link to be faster than down. Went back to store to cancel they called support who wanted to charge me full amount of plan!

  • ChicagoWhite Leeds Fan in Chicago (@ChicagoWhite) reported

    @ThreeUKSupport I was told when I took the contract i had 15 days if there were issues with the service. I have issues with the service as the coverage is non existent to minimal. I get less than 1meg down & quite often zero this was sold falsely.

    When are @ThreeUK collecting their award for the worst network in the UK? #shambles

  • Laurawa34473525 Laura walton (@Laurawa34473525) reported

    @ThreeUK your internet is absolutely shocking. It keeps cutting out. This happens daily. Unfortunately my phone plan is with @ThreeUK also. So when my work call cut out and I tried to go on my mobile hotspot, even that didn't work. Appalling service. I can't wait to leave.

  • ThatPlantTho Chloé Corcoran (@ThatPlantTho) reported

    @ThreeUK just spent the entire workday w/o phone signal or internet (we foolishly buy our internet from you too) with no warning or real explanation. My partner spent 5hrs in a beefeater carpark b/c he had to be on video calls. We pay you more than £180pm combined. Wtf??

  • adityapatnii Aditya Patni (@adityapatnii) reported

    @ThreeUKSupport @r0n4n21 The gentleman is right. Your network and mobile data are pathetic. The network is always down and that too in central London. Appreciate any assistance to get this sorted.

  • hope4sale chris graham (@hope4sale) reported

    @ThreeUKSupport @threeuk Am having issues with my Three 5G home router in the Belfast area BT37 0RD. 40kbps download, 85.2kbps upload. Have spoke to Three and raised an issue. Been happening over the last two weeks. Am having to tether my phone to my computer, just to get online!

  • ohthiagosilva88 JJvmes (@ohthiagosilva88) reported

    @ThreeUK don't think about re instating your sponsor when we are bought. You cut ties that's it @chelseafc should terminate your contract with immediate effect the outcome is of who buys us . We don't want your sponsor . I speak for every chelsea fan . Ur not wanted at our club
