    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

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • 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

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • 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 👏.

  • 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

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

    @O2 You have time to post these stupid ads but not respond to my multiple tweets about my continuous Internet connection?????

  • davieslee67 Lee Davies (@davieslee67) reported

    @O2 Steer clear of incompetent o2, inept in every way. Use another Mobile provider under any means necessary. You don’t need the grief of these useless morons. Owe me money yet restrict my service. Muppets

  • neeblee coffeefire (@neeblee) reported

    @O2 please help solve an issue I am a pay monthly customer and cannot text nhs number 80870. Similar issue with texting barclaycard on 85023. The message doesn't go through. Please help thanks

  • johng_victorius JohnG_victorius (@johng_victorius) reported

    @O2 2023: Being given some sort of customer loyalty having been with the company since 1999 aka BT CELLNET days would be nice.

  • Payno04 MPayne 💙 (@Payno04) reported

    Unbelievably poor customer service from @o2 once again. They owe money that they've wrongly taken from my account & every time I ask for a refund, they say they're putting me through to the correct department and instead cut me off. A complete joke! So petty too. 📞👎 #rubbish

  • andylutwyche Andy Lutwyche (@andylutwyche) reported

    @O2 Someone tried to access my account today so I called you to say that any activity on my account is fraudulent but you then ask me to give you my password or a verification code to confirm it’s me, something you specifically tell people not to do… pretty poor service…

  • paulmatt86 Paul Matthews (@paulmatt86) reported

    @O2 3000 Bce Person 1 “imagine a time where you pay to be able to make calls and use the internet on a mobile device, and then they hike your bill by upwards of 14%, and you experience worse signal and slower speeds. Imagine paying more for less service” Person 2 “I’ll pass”

  • ApertureReads Liam (@ApertureReads) reported

    @O2 Not the twitter-teams fault but awful customer service before. Had to speak to 5 people for a simple question about billing. Had RPI+3.9% increase explained to me twice, and had to go through security three times. And no answer given. Definitely switching.

  • FieldhouseTammy Tammy Fieldhouse (@FieldhouseTammy) reported

  • welshapplefan Rob T (@welshapplefan) reported

    @O2 I need to speak with someone asap about a complaint. Your off-shore call centre doesn’t understand the issue and was just about to send me £400+ which I’m not entitled to. Can some from UK contact me please
