    @O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

    @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

    none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

    Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

    @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

    Is there a hashtag for awful customer service from @O2 and/or @DHLParcelUK ? Asking for a friend.

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

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

    @O2 Thank you. I raised it in the O2 shop and they agreed it was and has always been bad. At the time they said to switch to 3G (that’s what they did) 🫣

    @O2 @virginmedia spent months trying to resolve incorrect default from Jan 2026.Multiple complaints have been incorrectly closed/ignored/been passed between departments. No deadlock letter closed my complaint without addressing my response. @LutzSchueler help! Comp unacceptable!

    @O2 why aren't you offering compensation for customers going up to 8 days without being able to stream anything properly on mobile Internet and everything really slow. Thank you for £25 off my £25 bill but this is getting ridiculous now. Ì've until recently paid £60pm for years

    @O2 Also trying to change my surname and your website won't let me upload my marriage certificate, even though it's in jpg. My local store in Romford wouldn't help at all.
