  • 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. #

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

    And the harrowing experience continues with @o2! Porting out within 14 day cooling off period of “new” contract seems to be a tough ask for #O2. Unacceptable, impolite behaviour of customer services while the farce from technical side continues. #O2fail! CC: @MarkEvansO2 @Ofcom

  • 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

  • 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

  • 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

  • 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!

  • 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

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

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

  • 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.

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

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • 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

  • 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

  • Steve_Edwards77 Steve Edwards (@Steve_Edwards77) reported from Hertfordshire, England

    @westspice @O2 Awful service for me 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

  • 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

  • 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

  • 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 .

  • 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

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • 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

    @O2 your customer services team really do take the absolute piss out of customers went into store yesterday spoke with someone over the phone they promised me a phone call back today and guess what….. NOTHING!!!!!

  • SEAMAC_VALET SEA-MAC VALET (@SEAMAC_VALET) reported

    . @O2 coming to your Livingston store because getting angry at Ai automated systems is boring now. Would rather sit and talk to a person and leave a great review for shop and staff and get my problems sorted in 15 mins than deal with you online or over phone.

  • taz3677 louise stone (@taz3677) reported

    @O2 hey O2 is there an issue with app usually log in using finger print but keep getting sent an email to verify when i verify same thing again please and thanks

  • Jopaco84 JoPaCo (@Jopaco84) reported

    @O2 cheers for knocking all signal off near me today. Planned works yet you never tell people in advance. I have loads I need to get done today, and can’t use my personal or work phone. Absolute morons.

  • khaansenser …………………………………………. (@khaansenser) reported

    spoke to @O2 as no signal on phone… their response… fixing a near mast that’ll take them another week… i hope their calls are recorded as this doesn’t seem right

  • __JamieA5h_ Jamie (@__JamieA5h_) reported

    Sick to back teeth of #o2 being absolute ****.. been like this for months. It's gotta be intentional. Worst network I've ever been on, by country miles @o2

  • KilleenFiona Fiona Killeen (@KilleenFiona) reported

    Anyone having issues with @o2

  • dickiemint1 Dickie Mint (@dickiemint1) reported

    @O2 It's impossible to simply email you with a problem! Are you hiding? My wife's auto topup has been taken twice. Why?

  • newtons1988 Sean (@newtons1988) reported

    @O2 the worst customer service support I have ever experienced, live chat that keeps kicking me out with 40 mins wait times, phone line that says they are not open and to call between 8am and 8pm when they are open!! Already waiting for free gift for 2 months and multiple calls

  • mazcalabria Maria Scalise (@mazcalabria) reported

    The Blue Monday prize 'play now' button is not working. It worked in the past. @O2
