  • 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

  • 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

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

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • 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

  • 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

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

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

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

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

  • 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

  • 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

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

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

  • 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.

  • 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?

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • 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

  • bradders2010 Bradley (@bradders2010) reported

    @O2 @SkyHelpTeam how do I report a blackout area? Intermittent connection where I work and not just me having the issue people on o2,sky and Tesco all having slow/dropping out connection despite having 3 bars.

  • emmajg 🌸 Emma 🌈 (@emmajg) reported

    @bt_uk Once I can contact my parents I get the info, I have to wait for them to get to an area with mobile signal & they call me. It's crazy it's only in South Wales near Chepstow yet no @O2 or any mobile company has signal so can't even call 999.

  • xLucyfx xLucyfx (@xLucyfx) reported

    @O2 Hi, I'm not longer a customer with you but I've recently had an email to say you owe me a refund and to provide you with my details. Is this safe and genuine please?

  • sternejohn John Sterne (@sternejohn) reported

    @O2 In my house at all times, it’s so bad that I’ve resorted to calling most people on WhatsApp. Trouble is whenever I get calls from anyone on landlines they can never hear me.

  • martynbroad Martin Broad (@martynbroad) reported

    @O2 @JessIsCuty Same here in Swansea, full signal yet no or poor service

  • HaloScotgal Sharon Wilkinson-G (@HaloScotgal) reported

    @JimmyCardiff @O2 I had the same trouble - if you choose the forgot password option it will let you set one. Pretty poor that never sent the email address and password info in the first place though…

  • matthewjorange ᗰᗩTT-ᕼEᗯ ᗰᗩKᗩᐯEᒪI (@matthewjorange) reported

    @O2 you have got to be the worst provider in the UK. NEVER ANY SINGLE. sort it out please.

  • palfreyman1414 Ravi Nair #FBPE #PerfectPorkPie #JohnsonOut#FBPPR (@palfreyman1414) reported

    @FelicityCloake @O2 ****.

  • palfreyman1414 Ravi Nair #FBPE #PerfectPorkPie #JohnsonOut#FBPPR (@palfreyman1414) reported

    @FelicityCloake @O2 I worked at a call centre once where a particularly slack staff member put a customer on hold, went out and smoked a leisurely joint, came back and took him off hold, and said: "I hope you enjoyed the music, sir."

  • andrewjminter Andrew Minter (@andrewjminter) reported

    @O2 I’ve had no signal on my phone for a week now; you said a mast wasn’t working (200m from our house), but would be by 20 May. Now it won’t be until 27 May. That’s 2 weeks without signal…do I get a refund and WHEN will the mast be mended??
