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

  • 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

  • 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

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

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

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

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

  • 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!

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

    @O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

  • 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.

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

    @O2 How did this shit happen

  • 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

  • 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!

  • 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

  • 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

  • MelissaPocock1 Amore della Cucina (@MelissaPocock1) reported

    @O2 is there an outage in Leeds…I have no network?

  • capnmac85 capnmac 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦 (@capnmac85) reported

    @O2 I have now with the help of the nice people at the o2 shop worked out there is a fault with the phone. This phone was given to me in February by @O2 insure. They are refusing to fix it without me paying an excess. I did not cause this problem. The phone was faulty.

  • notdodgy Roger Leitch (@notdodgy) reported from Solihull, England

    @O2 why does the local B90 4AJ mast go faulty EVERY week. 6 weeks in a row now, we get no service until it is repaired. You need better repair engineers as their repairs do not even last a week!!!

  • Burnside_5 Burnside (@Burnside_5) reported

    @O2 Seriously? How can I use the network checker to see if there is a known issue if I don’t have a connection?!? When finally out of the area and with 4g I could then see that there is an issue that will be fixed by end Nov, this has been going on for months. What am I paying for?

  • katieFHQ Katie Ann Grime (@katieFHQ) reported

    @O2 you call me off 0800 840 0202 to ask me how my complaint call went, when I say I want a discount because you can’t give me signal YOU cut ME off. You could of called me back as you called me in the first place #Shockingcustomerservice

  • mrguddah mr guddah (@mrguddah) reported

    @daniel_barnett @O2 Honestly the only thing that saves o2 from me leaving them is their excellent customer service representatives..oh God they are well trained compared to the competition

  • yelirtrauts S T U (@yelirtrauts) reported

    @daniel_barnett @O2 This happened to me a few years ago. They both refused to speak to the other, even when it was on speaker. I made them cancel my contract (that was a different drama), went next door and started a new contract with EE. Shower of ****. Nice to see some things never change.

  • Joe1080p Joe 💙 (@Joe1080p) reported

    @O2 is there anyone I can speak to that actually knows how to do their job and can fix my new account? Got a phone I cancelled, and my old number has been ported over after I told them I didn't want it to be and I was told it wouldn't happen.

  • JohnPaulBudd John-Paul Budd (@JohnPaulBudd) reported

    @O2 Bet she had no signal

  • discworld_girl Discworld Girl 🤩 #SackBorisJohnson (@discworld_girl) reported

    @O2 well, turns out some companies DO think I'm worth a basic contract! 14 years with you and you couldn't give me what @ThreeUK did when I never spent anything there.
