  • 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.

  • 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

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • Dave_Clarke_ Dave Clarke (@Dave_Clarke_) reported

    @O2 is it actually possible to talk to someone rather than the automated number which keeps hanging up? What phrase do I need to@say for this to happen. Your messaging service on the app is woeful it’s been 3 weeks trying to sort my issue #veryunhappy

  • MichaelJonesJTL Michael Jones (@MichaelJonesJTL) reported

    @EE @EE I think you need to employ more people to handle your social media platforms. You haven’t replied to ANHONE on this tweet. @O2 even managed to reply to someone on this thread and you still haven’t. Best network/customer service my arse.

  • frankie_franks1 ❤️ Fran ❤️ (@frankie_franks1) reported

    Awful customer service experience with @O2 this morning. Called to speak to an adviser regarding matching an online deal I had seen. The advisor chose to hang the phone up on me instead of discussing options. Utter disgrace! Certainly won’t be considering O2 in the future!

  • Beth_is_ Beth (@Beth_is_) reported

    Swear @O2 mobile data is just for a laugh, why is the signal so ****?🤨

  • AlanWordley Gom Schoolbag (@AlanWordley) reported

    @O2 as your app is next to useless, can you please tell me how to cancel a contract that has already ended but I'm still paying for!

  • NoTanAussieMiss Hayley (@NoTanAussieMiss) reported

  • BELIEVETHEREIS 𝕄𝕒𝕩𝕚𝕞𝕚𝕝𝕝𝕚𝕒𝕟. Politcally unaffiliated. (@BELIEVETHEREIS) reported

    @O2 I bought a Sim that had the 18gb promotion on it. On the packaging it read that 'as a new customer your ppromo will be applied automatically'. Mine has not. It still shows 6 gb on the website and on the phone app. How do i get this sorted please?

  • nicoleloisee nicole eloise 🏳️‍🌈♿️💀💄 (@nicoleloisee) reported

    @securedspirit @O2 I love that you do this bc complaints outweigh praise so much in customer facing jobs, like in the four years I was at Maccies we got TWO praise things (one for me obvs bc I’m amazing) so it really makes a difference when people do this 😭
