  • yasirkiani22 Yasir kiani (@yasirkiani22) reported from East Ham, England

    @O2 it’s been three weeks now and very poor customer service no response???

  • MCFCLondon Tueartsboots 🐝🌹✝️🇬🇧🇺🇸 (@MCFCLondon) reported from East Ham, England

    @O2 how come i can get a phone signal under the Thames on the Jubilee line but zero signal on Shooters Hill, SE18?

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before - I’ve now tested on both front and rear cameras with and without HDR and it bleaches every time. Is the product faulty @AppleSupport or is this an iPhone 12 issue in general. How can I fix it?

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • aydenwilsonHE Ayden Wilson (@aydenwilsonHE) reported from Hackney, England

    Anyone else lost @O2 signal?

  • J5752x Jay S. (@J5752x) reported from Paddington, England

    Went to @O2 #TCR to swap my monthly contract onto a prepaid card. I was told it has to be done over the phone and they can’t issue a new SIM in store. Went to @EE and asked if I could transfer my number to them. The seem enthusiastic

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 Hi, yes I’ve done both. Apps are so slow loading when wireless is switched off and service isn’t great on 3G or 4G. Used to be excellent

  • daveya90 David (@daveya90) reported from Wandsworth, England

    @O2 just went into one of your stores to upgrade my phone and experienced the worst customer service. Was told to recycle my phone with another shop in the shopping centre and be without a phone for 3 days cause they’d “give me a better offer” and told I could shop online instead

  • AledSmith Aled Smith (@AledSmith) reported from Camden Town, England

    @O2 why is it so hard to get your systems to work properly. Don’t give me automated messages telling me I am overdue with my bill when I am not. Then sort out your customer support. How can your AI engine be too busy to ‘talk’ to customers. Rubbish.

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Tottenham, England

    @O2 You have had this problem for the last 20 years doubt a self help guide will work. Ive made several complaints so end of contract I will be looking for a new service provider ...

  • silverback1809 Shane Pender (@silverback1809) reported from Bromley, England

    @O2 Is there an issue for WhatsApp videos on o2? Both mine and my other half’s WhatsApp has stopped playing videos were sent. I use some videos I’m sent for my job!!!! I’ve deleted the app I’ve contacted WhatsApp. Still nothing is working!

  • kostas1903 Esmer Ozan (@kostas1903) reported from Bexleyheath, England

    @O2 The UK’s number 1 network? Don’t make me laugh ! I’ve just switched from Vodafone to 02 and that was the worst decision I’ve ever made 🤬🤬🤬 I barely get 1 bar. My phone keep disconnecting in central london. Calls are always failing. 02 is my disappointment.

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before

  • PaulGrayburn Paul (@PaulGrayburn) reported from Romford, England

    @mobilemandan @O2 Just got 8Mbps down 🎉 Did get just under 300Mbps on 5G in London earlier but it’s still very patchy in the city.

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • yasirkiani22 Yasir kiani (@yasirkiani22) reported from East Ham, England

    @O2 having bad experience with o2 service after 15 year 😡😡😡

  • kieranbowley KB_UK (@kieranbowley) reported from Bexleyheath, England

    @O2 Sadly I am an enterprise customer. Any idea when they are going to be available?

  • hedaramusic hedara (@hedaramusic) reported from Hammersmith, England

    @O2 absolute JOKE of a service today. Got a deal offered to me by your retentions team TODAY, I ring back later to call it and no one with authorise it. Been passed to and fro for an hour and a half and got NOWHERE. The phone and deal I want is sat in my basket. Help.

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • Tony_Mattson Tony Mattson (@Tony_Mattson) reported

    My phone seems to have stopped functioning properly since my most recent iOS updates. Network connection rubbish. Apps not working. I now have a mobile phone that is useless while mobile. Is this an @o2 problem or an @Apple problem?

  • nicolasanderso1 nicolas anderson (@nicolasanderso1) reported

    @O2 what’s wrong with your network can’t make or receive calls. #phonewontwork

  • adison33601185 adison (@adison33601185) reported

    @O2 Restarting doesn’t work! Network checker says “Looks like a nearby phone mast isn’t working as it should, sorry. Our engineers are likely to be on the case already, and your service might come and go until we fix it.” N12 7AS. I’m literally at my wits end, it’s been 4 days!😤

  • TwtrMinstrel Peter Williamson Garland🇺🇦 (@TwtrMinstrel) reported from Edinburgh, Scotland

    A cold call last week from 'Plan' I foolishly trusted them. Now phone is cut off and they are ripping my phone bank a/c. Please Help me @o2

  • benltfc77 Ben Kennedy-Weeks (@benltfc77) reported

    @O2 Why is live chat not working on your website??

  • adamtooke Adam Tooke (@adamtooke) reported

    @O2 tomorrow will be 4 weeks since ordering my iPhone pro max, which one of your customer service ladies rang me to upgrade about I might add! She told me up to 4 weeks for delivery. Any chance I’ll get it soon? This is ridiculous!!!

  • squirrell_s Suzanne Squirrell (@squirrell_s) reported

    @O2 This is now 4 days of trying to renew a contract now told I need to wait potentially up to another 24hrs before I can start the process all over again but it will 72hrs before a manager can call me back I am loosing patience someone must be out there who can resolve this help me

  • G8AccountingLtd Wendy Bowler (@G8AccountingLtd) reported

    @O2 - just changed to you. Supposed to switch my no. but it's not worked. Only receiving some calls but not all. Spent ages on helpline but your staff can't seem to find a problem so now I have to go in store. Wish I'd not bothered. Massive pain. Not happy 😡

  • nicksagar Nick Sagar (@nicksagar) reported

    Hey @O2 !! How can you just justify charging me £7.20 per MB without notifying me of the charges on my arrival onto the Singapore network - my account is now suspended until I clear the bill but can not receive the pw reset code as my 3G is suspended!!! This is a joke!!!

  • curious_mind__ curious_mind__ (@curious_mind__) reported

    @O2 No online chat available for PAYG! Twitter handle ignores the tweets for help. On calling cust care they are least bothered and try to sell the products! They can’t even get a sim delivered. Bad experience even before starting with O2! I’m done ❌
