    @O2 don’t know what it’s so difficult for a customer service understand why my bill is double 2 only listen to what was a office party in the background to only hear the advisor come back laughing after me asking her to ask them to be quiet not very professional

  • Nish_xox Manisha 🇮🇳 (@Nish_xox) reported

    @O2 Hi, any reason why I have had any signal for the last week all around my area? Same for my family, what are we paying for if we can’t make calls/texts/use 4g?

  • safiya_amina_3 Safiya Amina Hafeji (@safiya_amina_3) reported

    I forgot to add, the @o2 advisor who took my first complaint is the same person who repeatedly asked the questions 'are you sure?', 'are you sure?', 'are you sure?'.

  • ColinPC62 Colin Parker-Chance 🌹🏳️‍🌈🏳️‍⚧️ (@ColinPC62) reported

    @O2 Yeah I know over three hours later! Thanks but you were not help at all even on the chat part of your website we’re you were advising you could circumvent GDPR rules by helping me get info on my daughters phone account! Incompetent doesn’t cover it!

  • benootral Shahaj (@benootral) reported

    @O2 @virginmedia You're a big joke o2 your service is disgusting

  • MickeyBrasco Micky Brasco (@MickeyBrasco) reported

    @O2 my mobile data has stopped all of a sudden. My o2 app says I have no data services but in my tariff says its 15gb per month. Tried to add a bit on but wouldn't let me and your messaging service is unavailable. What's the best way to contact someone to look into this?

  • DieselDragonUK DieselDragon (@DieselDragonUK) reported

    @O2 Can you please explain why my (very low demand) connection is being made unusable just so those on VoLt can experience „#WorldBeating” service? It’s not like I’m asking for MBs - A stable 300kbps would be enough! 📶 Or is this because @virginmedia happen to dislike me? 🤔

  • HeadLulli Lulli head (@HeadLulli) reported

    @O2 Eveyone do not go with these people they sold me a contract last week lied to me about the upgrade sweet talked me and now they don’t want to help because I found out they lied to me absolute disgusting scamming people the guy who spoke to me thinks he’s got away with it
