  • 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

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

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

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

  • 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.

  • 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?

  • 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

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

    @O2 is an absolute **** show ! If you think that paying insurance will support you in time of need you have been mislead ! On the phone to them for the past hour whilst abroad and I still haven’t had a solution. I am now waiting to speak to the 4th person #o2

  • stumartin74 Stu Martin (@stumartin74) reported

    @O2 Is the signal down in Wrexham?

  • RichardHesketh1 Richard Hesketh ☯️⚛⚕ Don't Call Him B***s. (@RichardHesketh1) reported

    @O2 have agreed to set up WiFi Calling on my partner's Samsung A21s due to seriously poor service. #WellDone them. @vodafone have ignored my requests and I'm left with no option but to leave them.

  • simonhall1974 Simon Hall The Infamous Infant ❤️✌🏻📷🏉☕ (@simonhall1974) reported

    @O2 help me out here, my contract was cancelled 2 months ago, yet you still text and email me stating my airtime plan payment is due.......I owe you nothing, nothing at all.

  • Miniv20 Mini Vara (@Miniv20) reported

    @O2 Wouldn’t mind not being hung up on by your customer service agents, messages replied to and your network actually working for me to make calls in my home

  • handsworth Handsworth Boys (@handsworth) reported

    @O2 still have a very poor signal - S60 5TZ - over 48 hours !!

  • mark_nelis Mark Nelis (@mark_nelis) reported

    @O2 your service in Torbay has been absolutely despicable! No "real" signal for about 2 or 3 months now and you refuse to reply to anyone who challenges you, I'm paying full money for a quarter of the service (along with countless others) yet you blank us.

  • bethanygordon_ Beth Gordon (@bethanygordon_) reported

    @O2 Everywhere really. I’ve been having one bar of signal at home when I usually get 4/5 and 4G. Same when I’ve been out and about recently too! Frustrating really

  • eatsruns Sarah (@eatsruns) reported

    @O2 I'm having trouble connecting to WiFi in tube stations on my new phone. Help suggests I need to download the O2 WiFi app. But I can't find any such thing in Google Play. Help?

  • bethanygordon_ Beth Gordon (@bethanygordon_) reported

    @O2 My phone service has been terrible for the last 2-3 days (on both phones I have) - is there a problem with your network?
