  • 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.

  • susancatton1955 Susan Catton (@susancatton1955) reported from Amersham, England

    @keelokeelo @O2 I have the same issue and have just spoke to Customer Services who were unable to give me any explanation!!!

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

    @O2 worst bloody network on the planet 6 FREAKING MONTHS I HAVE NOT BEEN ABLE TO USE MY PHONELINE DIE TO A MAST PROBLEM AND I AM STILL FORCED TO PAY FOR IT AND THEN HAVE TO PAY FOR ANOTHER NETWORK SIM JUST TO STAY AFLOAT KMT NEVER AGAIN

  • 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.

  • 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!

  • PieFaceMark mark (@PieFaceMark) reported from London Colney, England

    @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

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    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

  • savio_metal17 Savio (@savio_metal17) reported from Brentford, 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

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

  • TeamMegafreakPT TeamMegafreakTraining (@TeamMegafreakPT) reported

    @O2 Well my break at work is 11:40 and I'm in work till 9 after that so I am going to your store in Sunderland and I suggest it would be best they can help me and quickly. I've never actually known a company to not want to be paid, genuinely insane

  • beychain_putlee sartaj (@beychain_putlee) reported

    @O2, your roaming service in the US is abysmal

  • DreamChaserKiye ELGYY🤞🏾 (@DreamChaserKiye) reported

    @O2 It don’t help I’ve done everything even sent a new sim still don’t work just awful 🤬

  • MikeHuntTheMunt Mike Hunt (@MikeHuntTheMunt) reported

    @EnglandRugby @O2 Good to see Farrell not as a captain and all coming out about Eddie’s concerns for him in this role, upsetting referees, poor tackle technique and no plan B options as only plays one way. This will allow Jones to sub him just after half time from now on to go with plan B.

  • cdmk_catlady CDMK 🐾🇺🇦🌻 (@cdmk_catlady) reported

    @O2 Already did that . WA9 area, awful signal. Issues with mast?? It’s been getting worse past weeks, couldn’t load anything while outside today. Centre of town no signal.

  • Naked_stef stef (@Naked_stef) reported from Northamptonshire, England

    @O2 just been on phone to o2 customer services for over 30 minutes to speak to a real person . I am sill waiting for them to pick up the call. #veryAngry

  • SawdayJames James Sawday (@SawdayJames) reported from Manchester, England

    @O2 Hey - I have checked the guide. It’s not my device as it worked 100% better on a recent trip to France. It’s not the environment as this is something I experience everywhere (in Leicester, in Manchester, on trains, at festivals) - but your signal checker says I have good 4G.

  • Matthew10X Matthew (@Matthew10X) reported

    @O2 Had O2 Travel bolt on enabled but was charged £477 for using phone in the US, 3 weeks ago customer services said it was an error and would be fixed, still got charged though so now waiting on a refund

  • DreamChaserKiye ELGYY🤞🏾 (@DreamChaserKiye) reported

    @Black_King_Rass @O2 Bro I’m bout to leave , all week no signal in my house

  • WakeupP49062581 Wake up People (@WakeupP49062581) reported

    @O2 WHY is my 5G O2 signal not good at all in BS2 9QW? What would happen if I was in an emergency? I haven't been with O2 long and it's not fit for purpose right now. My phone is a new Samsung so it's not the phone. I'm frustrated.
