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

  • 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

  • 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

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 i have few screen shots of different areas when it’s service just disappears, call failed and only 1 bar, will share screen shots with @O2 3/3

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

    @O2 what is going on! 😭😭 Even when I have signal it's so slow!

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • 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

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 remember few months back when @o2 was down for nearly 2 days.. after that it’s service is going down everyday.. sometime when you are travelling and passing from certain areas O2 service will simply shift to 3G form 4g and sometime it will be No Serive at all 1/2

  • 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 .

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

    @O2 I have called O2 several times and also chatted online to a few people (Nooruddin for example).I also spoke to the 3rd party which don’t care and to the police which are busy with bigger problems.What it comes down to is YOU are charging me, and I am YOUR costumer

  • 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.

  • 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

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • LydiaElenaxo Λυδια-Έλενα (@LydiaElenaxo) reported from Tottenham, England

    After 11 years with @O2 they are really trying my patience today.. I’ve been a loyal customer and honestly upgrading has been horrendous with you.. I think @EE might be my new home from today

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    every single day your service going down ,moved to O2 from 3 , paying more getting less as compare to 3 but your service is kind of same , most of the places it just disappears, call failed, hardly one bar most of the time and no service at certain places.. v disappointing @O2

  • 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. #

  • _carljenkins_ Carl (@_carljenkins_) reported

    @O2 You think I've not tried any of that over the past year? Network is unusable in my area despite repairs being made on a local mast. Problems have only been over the past year and nothing is being done to fix them. I'll be switching to a network that has working 4g & 5g were I am

  • PClarke55 Dave Smith (@PClarke55) reported

    @O2 Don’t go to O2 they debited my daughters account for 30 pounds for a new phone. Did not give her the right documents and now over 1.5hours on phone getting the run around. No service go to EE or Vodafone least they are organised.

  • DBC_RYANGAMING DBCRYAN (@DBC_RYANGAMING) reported

    @cajogos @O2 mate 02 are **** ive spoken to them 3 times with the same issue each time ive been assured they have sorted it only to get the same problem everytime

  • MichellePenna10 Michelle Penna (@MichellePenna10) reported

    Tried to speak with @O2 online chat as the Brighton store NEVER answer the phone(have tried over 30 times since Saturday) and their advice was to call the Brighton store!! Absolute waste of my time and perfect example of not actually listening to a customer

  • Michael_JDean Michael Dean (@Michael_JDean) reported

    Having real trouble getting through on the phone to @O2 😔

  • toonharveylass Howay maan! (@toonharveylass) reported

    @O2 Hi. I upgraded my sim only in July and part of the offer was a £50 digital giftcard. I reveived an email to register this but had nothing since. 3 other people i know did this upgrade offer aswell and have heard nothing either. Can you help please? Thankyou.

  • rsrikigrps Srikant Ravuri (@rsrikigrps) reported

    @O2 One of your customer service deactivated by number when I wanted to take out additional contract and now I am left without a number for the last 5 days. Been calling "202" several times but no help, waiting for a manager's call for the last 4 days. is this level of service?

  • kartik_cs Kartik Chandrasekhar (@kartik_cs) reported

    @O2 Hi, could I please know why I got a reply within 2 minutes of my original and no follow up after that? I want to know how to make a complaint. I spoke to one of your colleagues on Live Chat, but that wasted 30 minutes of my time and I still don’t know what the issue is.

  • nicolahemphill1 Nicola Hemphill (@nicolahemphill1) reported

    I changed my mobile to @O2 and have had H+ data since! im supposed to have 5g or at least 4g. Beginning to wish I had stayed with ee because the Internet is terrible

  • FrostyFrosty_ Frosty (@FrostyFrosty_) reported

    @O2 Called and got through to someone. They’ve received no notification that my order will be at the store and then said it’ll be unlikely my phone will be in soon. Absolute shambles of a company. Disgraceful customer service.
