    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • cchelsealouisee Chels✨ (@cchelsealouisee) reported

    @WR01234 @RoFo123456 @O2 I got told when I ordered on the 15/09 that it would be here for the 22/09 - actually laughable how crap they are

  • AFrancisPhoto Andrew Francis (@AFrancisPhoto) reported

    @Innovationboxes @O2 It worked briefly, but now cannot login today. The support is very poor. They replied to my email a week later, told me they would make a payment to me today, as the payment process has problems, so far nothing has arrived.

  • cchelsealouisee Chels✨ (@cchelsealouisee) reported

    @WR01234 @RoFo123456 @O2 Literally just had the same problem. They're awful customer service! Don't offer it on pre-order if you're not going to be honest about delivery

  • BillAlexander4 Bill Alexander (@BillAlexander4) reported

    @O2 I’ve already done this, and registered to be notified, but there is no update. It has been down for most of the day.

  • Chad25216451 Chad (@Chad25216451) reported

    @O2 Join O2 as they have a special offer on….20gb data which they only give you GPRS signal…signal doesn’t work on trains whilst other providers do all for £25….what a bargain for the worst phone service provider in the UK

  • JohnCha02224835 John Chandler (@JohnCha02224835) reported

    @O2 please help I am constantly getting text from you I have tried switching off visual voicemail but it still persists I own a pixel 6a "Sorry, your number doesn't support Visual Voicemail, so we can't set it up yet. Please contact your service provider for help"

  • Bigsavi Ian Savigar (@Bigsavi) reported

    @O2 I have just spent half an hour being passed from one person to another and then cut off when I think I'd got through to who I need to speak to about my disputed bill. I've recorded this for my @Ofcom complaint.

  • kirstt89 kirsty smith (@kirstt89) reported

    @O2 I am very disappointed with the customer service I received at the middlesbrough store. When going in for a replacement Sim and a pretty straightforward process has now taken nearly 3 days to resolve because of the incompetence of member of staff! Still not resolved

  • realcharevans charlotte evans (@realcharevans) reported

    Hellooo @SkyHelpTeam there is no internet in Exeter and also helloooo @O2 the 4G has been so bad for the last month I cannot make things better by tethering my phone 😭 (Although I can watch cat videos on Twitter if I wait for them to load so that’s good) x

  • geoffslaugh rebecca💖geoff+gavin (@geoffslaugh) reported
