    @DeborahBiggs6 @O2 The issue of the accounts getting disabled or hacked is very frustrating and annoying especially when no respond and help from the support team whatsoever I couldn’t wait no longer so I reach Programmer_jock on Instagram and they got me back my hacked account.

  • M8Miyamoto Miyamoto Musashi (@M8Miyamoto) reported

    @O2 your support service is terrible! I can’t get through on the phone - left waiting for hours. Can’t msg an agent on your app because it says “agents are forever busy”! How do I contact a real person? VERY close to canceling my contract with your sub-par service! #awfulservice

  • WilliamNB 🚲 Will is too honest to ever be an MP 🇬🇧🇿🇦 (@WilliamNB) reported

    @lastnotlost @giffgaff Giff Gaff runs on @O2, so the underlying issue is O2's crap service. I'll need to jump to either EE or Vodafone. I don't like either, but am forced to do this

  • katiecutspaper Doily Parton (@katiecutspaper) reported

    @o2 Can you help? My phone shows strong 4g signal but no internet is working. It’s not ideal when I’m trying to sort out getting to the vaccination centre 😫

  • Twisted20k Mike (ノ◕ヮ◕)ノ*:・゚✧ (@Twisted20k) reported

    @O2 Yes, still getting the same issue

  • MikeyCycling CyclingMikey tired of road crime. 🇪🇺🇳🇱🇿🇼 (@MikeyCycling) reported

    @AusterfieldM @WilliamNB @O2 Just find whichever network has best signal and data rates at your locations, and then go with that network. Never expect service from any of them, they are all crap. There are maps of mobile coverage, but I suggest testing with friends' phones or just buy some PnG SIMs.

  • Kattze22 Kat🏳️‍🌈✊🏾 (@Kattze22) reported

    @O2 I need my business account made into a personal one. I tried calling your phone lines but I was on hold for over half an hour, can you help me?

  • WilliamNB 🚲 Will is too honest to ever be an MP 🇬🇧🇿🇦 (@WilliamNB) reported

    @KarlOnSea @giffgaff Oh no! @O2 (or anything running off O2) is firmly out of the question. Ultimately it's their crap service that's the problem
