  • chris_reed Chris Reed (@chris_reed) reported from Hillingdon, England

    @O2 any Ida how long your site will be down for? I want to get a bolt on that works for Turkey, and I’m just about to take off…any advice?

  • Rochdale_Cowboy Craig (@Rochdale_Cowboy) reported from Maidenhead, England

    Took out an @O2 account as part of some 'volt' deal with @virginmedia. My god O2 are bad. Apparently you have to wait a few months to access your account online to wait until their systems "catch up" for new joiners. Shouldn't have bothered.

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    The is very cathartic after 25 years with @O2 I’ve left for @VodafoneGroup the o2 customer care and support is utterly woeful. And having given them so many chances I’ve had enough, so over to you vodaphone can you step up

  • ChatanG001 C (@ChatanG001) reported from Wokingham, England

    @O2 really shocking customer services today. All i want to do is pay off my device and it takes 3 people almost 45 minutes to even be able to do that!!! Stupid.

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 will I get final bill? I’ve loved to another network and want to cancel direct debit

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • carboncoach Dave Hampton 🌍🌳 (@carboncoach) reported from Marlow Bottom, England

    Anyone else having problems with the way @EE seem to measure monthly data use? EE are telling me I’m using significantly more -on average-and over a prolonged period- than I ever did on old @O2 contract (since switching: to save £1pcm) Nothing else has changed Over to you @EE

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 worst customer services, ring 202 to pay off phone and they cut me off then don’t answer, told on chat to follow link to chat to someone else who tells me they can’t help and ring 202! Going round in circles no wonder once paid off phone I’m leaving!

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 I was told a number would port over in 3-4 hours. 24 hours I am still waiting. Help please!?

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • crippsy_99 Stephen Cripps (@crippsy_99) reported

    @O2PriorityUK @O2 I 'won' some can's of Guinness a couple of months ago on the priority app.. I never actually received them though.. what happened to them?

  • DanielJamesKni1 Daniel James Knight (@DanielJamesKni1) reported

    @O2 never have I known it so long to cancel my contract with your company, I will phone again tomorrow which will be the third day in a row.

  • girllondon87 Stacey (@girllondon87) reported

    @O2 Hey, yes it is the same area we spoke about before. Can you give me an idea of when it is going to be sorted? I’m currently paying for a tariff that I can’t even use because of this issue. It’s been going for 3 months and it’s really frustrating to say the least! Thanks, Stacey

  • natashakearns_ 𝐍𝐀𝐓𝐀𝐒𝐇𝐀 (@natashakearns_) reported

    Erm @O2 can you please tell me why I just came through to someone else’s phone call with an adviser? I’ve just heard their whole name and conversation.. I put the phone down the second I realised it was another customer.. not really professional surely!! 🤨😳🤯

  • DK1_DK1 David K (@DK1_DK1) reported

    @O2 My mom was the victim of identity theft and had a fraudulent credit search from O2 on her credit file. You agreed to remove it but 8 months later it is still showing, despite being promised multiple times, logging a formal complaint, is there a regulator we can complain to?

  • karleburford Karle Burford (@karleburford) reported

    I recall when 3G was heralded as the future - now it means no signal. Then 4G was a new beginning but now means I may make a call but don’t try the internet. 5G is a game changer but has never worked in Bristol for me. @O2

  • Sammiebutler88 Samantha Bull (@Sammiebutler88) reported

    @O2 So @O2 I'm starting to wonder why i pay my phone bill when still signal is appalling. You tell me to use WiFi calling instead of fixing network issues. What happens when I'm somewhere that doesn't have Wifi such as when I'm at my grandmothers house and may need to call family?

  • LilacNannie LilacNannie (@LilacNannie) reported

    @O2 And that’s why no one should get a #Tescomobile on #o2 network - you don’t take responsibility for your failure. Take note people...

  • bjorn6 Michael Walker (@bjorn6) reported

    @PatrickMcEnroe Nadal has made 2 WTF Finals @O2 I attended the one in 2010 against Federer. @Wimbledon follows the computer rankings in 2021. This isn't new news!

  • kimmi_93 Kim (@kimmi_93) reported

    @O2 Since I’ve had a text saying your turning my 4G off my phone isn’t working probably and going really slow. I don’t pay £70 for nothing
