  • 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

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

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

  • 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

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

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

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

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

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

    @O2 How did this shit happen

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • CBrackenArtist Catherine Bracken (@CBrackenArtist) reported

    @O2 I cannot even call my 02 because of this issue! It's been weeks now and still nothing sorted.

  • TheNeensSpeech Nina Salome✨ (@TheNeensSpeech) reported

    @O2 why have I had no service or 4G all day? Was fine yesterday.

  • dean_marchmont dean marchmont (@dean_marchmont) reported

    @O2 after 15+ years of being one of your customers i have decided to take my custom elsewhere!!! Your decision to merge with Virgin and move your callcentres to whereever they now are has been the worst decision ever made by your business I have never received such awful service!

  • davidng68 David Ng (@davidng68) reported

    @O2 Phoned yesterday and was told to wait 24 hours for the email with invoice to arrive. Still nothing. Can anyone help?

  • neilwallace403 Neilwallace403@gmail.com (@neilwallace403) reported

    @ezzeeegooner @O2 @SkyUK I live in the middle of nowhere and Vodafone Wi-Fi calling is excellent at home. I don’t have too many problems with the signal as a lorry driver I’m all over the country and very rarely suffer signal problems

  • emzlewie Emma Lewington (@emzlewie) reported

    @O2 been a customer for 15 years absolutely appalling customer service today being pushed for pillar to post hung up on 3rimes wrong advice from your agents and taking money I have not authorised you to take. Absolutely ridiculous

  • CBrackenArtist Catherine Bracken (@CBrackenArtist) reported

    @O2 You have got to be kidding? Handy tips? I don't want to be faffing around when I pay enough for my 02! I am still having intermittent network. I want this sorted and some sort of compensation! I missed important doctors calls because of this! Please get back to me. Thank you.

  • Jewel_Crush_Axe EnviroComms Jewel, PhD 👩🏽‍🎓🧪⚗🌍🌎🌏 (@Jewel_Crush_Axe) reported

    @lskains @ThreeUK @O2 They are pretty horrible. I'm changing too

  • tomnixon Tom Nixon (@tomnixon) reported

    @patrickandr @O2 Thanks for the recommendation. Contrast that level of service to @o2 not even bothering to acknowledge this tweet. I’ll check out phonecoop. Which network do they run on?

  • CamillaLatham30 Camilla Sally Louise Latham (@CamillaLatham30) reported

    @O2 as much as love being a customer with #o2 there is a downside especially when you have to phone up to ask to pay off remaining contract. Would be easier especially if you’re disabled like me. And sometimes it’s easier to pay on the app/website. Please take this on board.
