    @judithjewelz @ThreeUKSupport Hi ruby! I’ve just spoken to three who have confirmed there has been a data breach as the issue with the outage caused our called to be “diverted” to those random numbers

  • c_h_pugh Christopher Pugh (@c_h_pugh) reported

    @ThreeUKSupport My service provider has removed a nearby mast, causing reception problems on my simple 2G phone. I am considering your network (on PAYG). If I buy a 3G phone, how much longer will you support the 3G network before it is decommissioned in favour of 4G/5G? Thank you

  • philrandal Phil Randal (@philrandal) reported

    Once again, my partner isn't receiving OTP SMSs from @santanderuk on the @ThreeUK network. @threeuk tech support are useless

  • PaulDooley17 Paul Dooley (@PaulDooley17) reported

  • ShaunSandx ShaunSanders (@ShaunSandx) reported

    @ThreeUKSupport Well its pretty poor from three don't you think ?

  • itsmarcie_x - Marcie (@itsmarcie_x) reported

    @AQ74410 @ThreeUK How wasn’t there a data breach when I had multiple miss calls when I called back they are people I don’t know saying I’ve called them! All while I was trying to call my grandparents and doctors never called those people before who I had miss calls from

  • itsmarcie_x - Marcie (@itsmarcie_x) reported

    @ThreeUK @ThreeUKSupport Why have a lot of us had our phone numbers being calle day random people saying we called them in the outage yesterday? Isn’t this a data breach?

  • shazzah_harm Shae Harmon (they/them) (@shazzah_harm) reported

    @ThreeUKSupport @hex This is absolutely ridiculous. I've also had issues with Three support in the past and it's atrocious. Calls and calls, trying to speak to an actual human. Being told to call back again and again. So unreliable

  • roxie_ndls Roxanne (@roxie_ndls) reported

    @ThreeUKSupport Im annoyed that a company as big as three wouldnt just hold their hands up and say okay something went wrong instead of trying to blame it on something else when clearly just by looking at your twitter page it was a wide problem
