    @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

    @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

  • 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.

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

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

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

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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

  • 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

  • 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

  • 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?

  • 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

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

    @O2 trying to upgrade on app and main website but when I choose it crashes can anyone help

  • 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

    @O2 placed a click and collect order on the 10th March as it said we could collect same day, still nothing despite numerous chasing. I was assured the latest it would be available is today but again nothing. 🤦 it wouldn’t be too bad but the current phone is no longer working

  • m4wds1 joe mawdsley (@m4wds1) reported

    @O2 If I just cancel the direct debit will that be OK if not what should I do

  • wayne386 Wayne R[]berts 👌 (@wayne386) reported

    @O2 Honestly no, for a couple of reasons 1) o2 signal near me is shocking at home 2) I’ve always found your data speeds to be err slow at best. So I’m not gonnna commit to pay monthly just for a proof of concept. Thanks anyway

  • MathThyMod Terry Allen (he/him)🇪🇺 (@MathThyMod) reported

    @AdamRutherford @O2 I left @O2 because of customer service.

  • _roballen Rob Allen (@_roballen) reported

    @O2 my experience is that the O2 connection drops away when the environment is busy. Is there enough capacity in Cheltenham? My service is barely useful

  • SarahByers15 Sarah Byers (@SarahByers15) reported

    @AdamRutherford @O2 I'm getting hung up on more and more by customer service lines, feel like it's the go-to move when they don't want to deal with you.

  • politediscuss Mr A C 🇺🇦 Слава Україні (@politediscuss) reported

    @AdamRutherford @O2 "Is there anything else I can help you with today?"

  • dodger0703 Captain Hindsight (@dodger0703) reported

    @O2 Hi just recieved my new sim card, transferring number from virgin and sent PAC code on Friday. My virgin sim has now gone to Emergency Calls Only, how long will it be until my new sim has that old number?

  • sibbo1980 justin sibbons (@sibbo1980) reported

    @O2 I've sent you guys an DM, could you have a look and help please. Your customer service is nortirosly slow in responding to emails and this seems to be the only function to talk.

  • _DavidCrompton David Crompton (@_DavidCrompton) reported

    @O2 why did one of your customer service agents place a bar on my account because I’m only receiving text messages from certain networks
