    @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.

  • 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

  • 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?

  • PhilipJReynolds Philip J ReynoldsTV 🎥 📻 🎙 (@PhilipJReynolds) reported

    Hi @O2 outstanding customer service today. First you increase my bill (didn’t mention that during the fancy new upgrade) then I’m on hold for 35 mins? I ask your staff about a data issue then they hand up? I should have went with advise & gone with @EE

  • farrenciaran Ciarán (@farrenciaran) reported from Blaydon-on-Tyne, England

    Hey @O2! 👋👋👋 You are really starting to make me angry. Why is my internet connection very slow, even when on 4G. I cannot deal withe pausing videos, apps and webpages not loading. Sort it out!

  • Baigrie1985 💚Marie💚 (@Baigrie1985) reported from Edinburgh, Scotland

    @O2 I spoke to an advisor in store they said they couldn't help me as I'm pay as you go she said she could only help me if I was a contract sim

  • JackSTXR ᴊᴀᴄᴋ (@JackSTXR) reported

    @O2 Have been appalling lately. Mobile data is extremely slow and does not work properly (including 5G) and text messages are taking hours to receive and to think I pay £80 a month..

  • Natalie80436441 Natalie (@Natalie80436441) reported

    @O2 Hi O2 just to make matters worse I sent a formal complaint 3 weeks ago and haven’t heard anything back.

  • caztoan caz toan (@caztoan) reported

    @O2 you seriously need to sort out your customer service. I understand mistakes are made but you took money from my husbands account in December, still waiting for the refund. He has phoned every 2 weeks and you've promised its been sent. Time to withdraw all 4 of our accounts

  • YamaEmilie God only (@YamaEmilie) reported

    @IVP_SUCKS @nathan06320834 @O2 Oh maybe someone should then introduce something like maybe to tackle issues like that in case can be a contributing factors

  • sdb Steve Bentley (@sdb) reported

    @o2 do I really need an email, SMS and app push alert telling me that my bill - which is paid by Direct Debit and identical to every other month - is ready? A heads up if it's unusually high makes sense, but 3 separate notifications about a non issue?

  • stevicoos Ojeaburu Stephen (@stevicoos) reported

    @O2 I must not be debited wrongly or I pick up this issue legally

  • goonerlgh Lawrence ****** 🇺🇦 (@goonerlgh) reported

    @O2 why do you block numbers using the 18001 prefix that is for the RelayUK deaf persons call service??? Why would you do that???
