  • NasiraKasmani Nasira (@NasiraKasmani) reported from Maidenhead, England

    @O2 unbelievable service from the #CustomerService agent today, so rude lady called Ambreen kept speaking over me. Unacceptable that staff have the audacity to speak to customers in such a manner and instead of resolving an issue escalate it to another level. Who do I complain to

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Brentford, England

    @o2 can you fix your network in Westfield as I’ve tried to FaceTime my mom more than 50 times the calls have been dropping all the time its sucks paying almost £90/Month and you don’t get basic network coverage inside the mall. Not a happy customer anymore.

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • jayblake_ Jay Blake (@jayblake_) reported from Marlow Bottom, England

    Dearest #02 @O2 I do wish all your customer service people were as helpful as the person I spoke to today. Sadly there were several trees killed in the printing of a years mobile bills, which I was told was required. Todays agent simply gave the info I needed in a 5 min call

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • LeeButterley utterlee (@LeeButterley) reported from Brentford, England

    @wheresnicktoday @elgobsucram @thisisryanon @O2 @EE When I lived in Manchester the O2 4G was so bad I had to switch to EE.

  • jackaarondavies Jack Aaron Davies (@jackaarondavies) reported from Richmond, England

    @O2 Not everywhere, but your 4G coverage in SW London is poor. I haven’t had 4G in Raynes Park since I moved there a year ago.

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Hillingdon, England

    @O2 It’s doesn’t help!!!!! It’s getting frustrating day by day been with @02 nearly 7 years and it’s getting worst day by day. No proper coverage. There’re much better network providers in the U.K. that provide better network and customer services it’s time to make a change!!!!!!!

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Hammersmith, England

    @o2 can you fix your network in @westfeild #London as I’ve tried to FaceTime my mom more than 50 times the calls have been dropping all the time its sucks paying almost £90 pcm and you don’t get basic networks. Not a happy customer anymore.

  • AikSaath Aik Saath (@AikSaath) reported from Slough, England

    @sabia_hussain @SEGROplc @O2 SEGRO have checked to see if the theft was on the estate itself. We'll see the young people right - just thought it might be worth reaching out to our 'bigger cousins' to see if they could help. Good to hear they didn't find anything in your car. 👍

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • DamianPDavis Damian Davis (@DamianPDavis) reported from Spelthorne District, England

    @paddyguy51 @Ker_Anderson @Phonemast Do your self a favour and swap to a network that actually works, i.e. anyone but @O2

  • timlimbim Tim Cawte (@timlimbim) reported from Maidenhead, England

    Wow @O2 honestly cannot believe how poor your service was this evening. Incompetent advisor with seemingly unusable (almost useless) systems. #complaint #poorservice

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • NeilNutbeam Neil Nutbeam (@NeilNutbeam) reported from Hillingdon, England

    @O2 why is the network and 4g soooooo bad. Well I say 4g, I never get 4g most of the time. And even if it does say 4g it’s rubbish and slow, stuff still doesn’t load. A lot of the time I have to turn 4g off and change it to 3G for it to work. Rubbish

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • CorinaWieland Corina Wieland (@CorinaWieland) reported from London, England

    @VictoriaGoodyer @O2 Exactly what I will do! I was hoping the more expensive monthly rate (to other providers) is justifid by the costumer service. How wrong was I! Fed up with the poor service, signal cover (in London!), weekends without data and now this.

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able
