    @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?

  • 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.

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • 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

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

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

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • 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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • ShannonBundy Shannon Bundy (@ShannonBundy) reported

    @O2 I called yesterday about a failed sim swap, the person I spoke to did it manually and it appeared to be successful this morning as I was able to make calls etc. but since this morning/early this afternoon I’ve not had signal despite restarting the phone many times.

  • AliJLab Ali L (@AliJLab) reported from Bournemouth, England

    @O2 If you are investing, I’m not seeing much evidence of it. The service in the Bournemouth area can be pretty abysmal- it might say 5G on my phone, but that doesn’t mean anything.

  • HiringinEMEA Heather Brady (@HiringinEMEA) reported

    @virginmedia @TheBHF @O2 Please can I have postal address to cancel.

  • deLaceyMusic de Lacey (@deLaceyMusic) reported

    @O2 Hi @O2 it's now been well over 48 hours. This is very, very poor. Please can someone remedy this. If I ever move back to the UK, I will think twice about returning to O2 at this rate. Thanks.

  • 4realnaestyles_ naè. (@4realnaestyles_) reported

    @O2 you and your stupid money management team department are starting to piss me off badly!!!!! I will leave this network and go elsewhere.

  • AmeetGonsai Gonsai (@AmeetGonsai) reported

    @O2 why is your reception in my@home area so bad!? It’s been like this for years. I’ve reached out to you in the past and it’s never fixed. If my broadband is down I need to be able to use the internet to check things for my severely elderly and sick parents. It’s useless!!

  • MrsIrons73 Zoe Irons (@MrsIrons73) reported

    @O2 just had a call from this number +44 20 3333 4883 saying they were investigating a number of reports of poor service in my area- i nearly fell for it because your service is terrible! Assume it’s a scam though?

  • dalotos Clan MacArthur (@dalotos) reported

    @virginmedia @TheBHF @O2 Customer care is appalling and trying to leave is a terrible customer experience. You can't cancel contract online. It has cost me hours (days for a confirmation email) and once you get through to the disconnection dep. (3x), there's no guarantee you won't have to go do it again.

  • 5elementsuk Tony Willis (@5elementsuk) reported

    Another day with O2 business wasting my time. Surely it cant be that difficult thats your business. Even the automated message on customer service tells you wrong info. If you send the sms it tells you then you get a response saying that option no longer works @O2 @o2businessuk

  • TechwithLee81 Lee 🇬🇧 (@TechwithLee81) reported

    Had a message from @O2 CEO office stating they're looking into my issue and will respond in 3 working days. It's now been 5. I sent an email yesterday and got no reply. It seems O2 are just a **** company.
