  • 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

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

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

    @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

  • 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

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • 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

  • 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 .

  • aktyrrell Andy Tyrrell (@aktyrrell) reported from Walthamstow, England

    @harwood_steve @O2 @EE EE service is shit around Chingford guys I work with never get a service I'm o2 never had a problem. Probably the country you're in. Plus we always get upgraded at the o2 by the o2 Angel's.

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

  • 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

  • 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

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • 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

  • 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

  • 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!

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

  • 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. #

  • 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

  • Halliwell80UK Joshua Halliwell (@Halliwell80UK) reported

    @O2 Still not resolved!! So you want me to keep chasing you guys rather than your huge company resolve the issue and treat people with respect! How about train your staff rather than making ex customers and customers keep chasing you while you destroy peoples lives?

  • hannahjbuswell hannah | fan (@hannahjbuswell) reported

    @O2 customer service from o2 is absolutely diabolical !!!! 😡🤬

  • friesnshake Fries&Shake (@friesnshake) reported

    Hi @O2 - been having signal problems with our local mast for months now. Getting a bit tedious of only having one bar of signal when my monthly contract payment isn’t exactly cheap!! #o2down

  • maddenstravels Danielle Madden (@maddenstravels) reported

    @O2 @SaBrky I’m having the same issue, can’t even get into the network and when I do nothing works! I’ve tried all the tips but no luck

  • Halliwell80UK Joshua Halliwell (@Halliwell80UK) reported

    @O2 You also incapable of closing accounts and keep billing people! Instead of chasing new customers you need to review the capability of your colleagues because you’ve treat me appallingly and still not resolving issues

  • colbal1 Bonko (@colbal1) reported

    @O2 Great that you are investing in 5G but I can hardly even get a phone signal never mind data indoors in a Glasgow suburb. O2 says signal fine but three households near me are all the same

  • CryptoKingBob King Bob (@CryptoKingBob) reported

    @O2 Hello! Yes the cashier tried about 5 times including entering the code manually. The drinks were on the offer (1 carling and 1 pino grigio). Another customer behind me used hers fine.

  • Ethelready2 Ethelready (@Ethelready2) reported

    @O2 why have you switched off 4G calling from my account? Presumably credit for this unannounced cancellation of service will be immediate?

  • ClaireT08086454 Claire Thomas (@ClaireT08086454) reported

    @O2 can’t enter any of the prize draws keeps saying there was a problem try again later?

  • steepair Stacey 🌻 (@steepair) reported

    @O2 please help. I tried to change my tariff the other day cos I use way too much data and have to buy bolt a few times a month. Low and behold I run out again and was ready and willing to add more, but I can’t. It says to cancel my new tariff which I thought I did, but no joy.
