    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

    @O2 How did this shit happen

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • 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

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

    @BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Miss_GScience Tegan (@Miss_GScience) reported

    @O2 A brand-new phone was offered, but only at £14 more per month. I eventually accepted the device just to end the stress, not because the issue was handled well.

  • lunabhuna_ luna 🌙 (@lunabhuna_) reported

    @O2 I'm having trouble cancelling my sim only contract. I am within my 14 days cooling off period

  • Andree1990 Andree Wood (@Andree1990) reported

    @O2 please can someone message me regarding an urgent issue? Thankyou

  • egyptian_irish Kareem (@egyptian_irish) reported from Kilroot, Northern Ireland

    @O2 Migrating from O2 PM to O2 PAYG has taken 7 days so far, 3 phone calls of over an hour each and teams of people who have no idea what they are doing. Your customer service standards are shockingly poor and your back office processes are terrible. I can't wait to leave you

  • DarrenCoates Darren Coates (@DarrenCoates) reported

    @O2 when are customer services open?

  • MikeC0616129283 Mike C (@MikeC0616129283) reported

    @O2 O2 Plus Tariff, unable to connect in Japan (is listed as O2 Plus Data Travel Zone). SoftBank asking for Money when using O2 SIM. 4g&5g Signal Goes up and down randomly when sat still. Data Connection Log V.ODD. UK Banking Connection Firewall Alarm on Japan Mob Network. HELP!

  • lunabhuna_ luna 🌙 (@lunabhuna_) reported

    @O2 @O2 I have updated my settings. You may DM me. I will share my account details to cancel the account

  • Casserly_Rock James Casserly (@Casserly_Rock) reported

    @Vivsnewtwits @O2 Totally unprofessional, rude and basically showing contempt for you. Unacceptable.

  • xFaLLiNGxSnoWx2 xFaLLiNGxSnoWx (@xFaLLiNGxSnoWx2) reported

    @O2 Find someone to talk to me on here. My patience for this **** is wearing extremely thin.

  • Vivsnewtwits Vivi Rivi (@Vivsnewtwits) reported

    @O2 your "customer services" start calls with "hi dear" Do you think that's appropriate? It would be inappropriate if they were competent. As they are not, struggle to speak intelligible English and cannot resolve issues, it's particularly offensive.
