    @O2 Poor customer experience in-store today. Disappointed to say the least.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @virginmedia @O2 Amazing how today the internet in our area went down. It’s back on yay. But now our virgin box won’t connect and it’s my fault. Well done virgin. Contract finishes in a month guess I’m off!

  • meesterbeel Peter Philip 💙 (@meesterbeel) reported

    Hi @O2 is there a problem with the App / Website at the mo? Trying to add a O2 Travel Bolt On but page has a message to say ‘This information is not available at the moment. Please try again later.’ Any indication when they will be available again?

  • Reklaw22306168 Reklaw (@Reklaw22306168) reported

    @O2 So what are you going to do about this absolute fiasco from O2 towards my son. Are you going to instruct a manager to call him with options? Only a manager can resolve this issue. In other words, I want the ***** grinder. Do you understand?

  • Fraaanx33 Fran (@Fraaanx33) reported

    @o2 you’ve affected my credit score, not had the decency to email me back, and i’m being given the wrong advise of how to return this stupid upgrade every time i ring. Get your act together, your customer service is appalling

  • reynards2016 Alex McDonald (@reynards2016) reported

    @O2 a comms co who can’t communicate. Can’t claim on o2 insure due to all day outage. Still waiting for call back…. #getagrip #poorcustservice

  • MaynardsKeyne Maynards Keyne (@MaynardsKeyne) reported

    @O2 comically bad customer service. “we can’t see your bill” - any yet it’s £100 more than it should be? Then, India. Listen, I’ve worked in India, it’s not somewhere for call centres. Once I’ve sorted this out, you’re gone

  • stevebell01 Steve Bell (@stevebell01) reported

    @O2 It's been a week since I first tried to upgrade and every promise to resolve technical issue hasn't happened. I need to know who I can speak to. Not the upgrade department. I've spent over 3 hours on the phone. Customer for 15 years.

  • peterkin1010 Peterkin2020 (@peterkin1010) reported

    @bazc1982 @O2 Which of course is why everyone subscribes to O2. WORST network by miles here in Cardiff. There is some hope that Liberty Global will start placing more emphasis on sorting it out rather than bullshit 'woke' stunts.

  • Chrissie_Pilk Chrissie (@Chrissie_Pilk) reported

    @O2 I am still awaiting a reply following my complaint email on Wednesday. Impossible to speak to anyone and still without my phone due to incompetence. Can someone please contact me ASAP

  • ecsg1798 E Charles (@ecsg1798) reported

    @O2 No that's not the issue. Can you DM?
