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

  • 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!

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @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.

  • 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

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • 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

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

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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

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

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

  • stourdave Dave (@stourdave) reported from London Colney, 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

  • 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!

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

Latest outage, problems and issue reports in social media:

  • amiemyoungx Ames (@amiemyoungx) reported

    Been trying to get through to @O2 for 3 days, no one answers the phone even after waiting 40 mins Great customer service 👍🏻

  • RuthHolliday13 Ruth Holliday (@RuthHolliday13) reported from Hammersmith, England

    Still within my 14 day grace period with @O2 having so much trouble actually speaking to a human about my issue I’m so tempted to cancel cause this stupid system keeps just hanging up on me and it’s been 3 days since I requested they transfer my number… not great

  • TBarnesGrasmere Tom Barnes (@TBarnesGrasmere) reported

    @O2 no service for 4 days and absolutely nothing offered as way of an apology. Customer service/satisfaction shocking

  • SallyStillTalks SallyTalks (@SallyStillTalks) reported

    It's going to take a person somewhere about 2 minutes to push the buttons and issue me a refund, @O2 just give me that person's email address why am I having to call this out on twitter?

  • helenr35 Helen (@helenr35) reported

    @callmeprimey @O2 I use O2 recycle for years usually in the store. I’ve had any issues before now. It’s a well known fact people are being misinformed there’s an error on their phones when there is not. It’s an utter disgrace!

  • jamalpatel jamalpatel (@jamalpatel) reported

    @O2 Been trying your chat for 3 days now, just says it busy. Also ringing customer services for 3 days, just can't get through. I'm a new customer who has just joined and believe me I am not impressed

  • Squirrelchez Cheryl Jones (@Squirrelchez) reported

    @virginmedia @O2 Sort out your **** - the tv has gone off again! Even if we try to ring you, it is either engaged, cuts you off after an automated message, or says the number isn’t recognised - despite being the same number (150) on every attempt!! And your website isn’t working properly either!

  • darrenwhitehall Darren Whitehall (@darrenwhitehall) reported

    @O2 has the worse customer service in retail history. I am so angry. I just want out. All I want to do is pay off my device plan. The only line that picks up the phone is the upgrade line and that takes 3 minutes. Payment late is a disgusting bad.

  • cfc_blue2 ChelseaGOSSIP (@cfc_blue2) reported

    @O2 tried signing on with o2. The worst experience I've ever had in 1 single day. Rude woman hanging up the phone, unhelpfull , lies not able to provide a simple service. See a deal on o2 just avoid!

  • waynestanbrook Wayne Stanbrook (@waynestanbrook) reported

    @O2 just spent 40mins trying to get through to your support to activate an eSim to be cut off! …..not happy 😡…..can’t event start a live chat. Why do you make it so hard to speak to?
