  • allyc375 Alison Cameron🐟 (@allyc375) reported from Kensington, England

    @ShieldingG @O2 Now there’s an idea. I wonder where the cleaners put it. I’ve only ever used it for my Dalek thing - never plunged a sink in my life.

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 Hi, yes I’ve done both. Apps are so slow loading when wireless is switched off and service isn’t great on 3G or 4G. Used to be excellent

  • Mr_ISC Pasha (@Mr_ISC) reported from Wandsworth, England

    Serious network issues with @O2 - calls not connecting or dropping after 30secs all morning!!

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 are you having power problems in the SW London area? I can’t get a service which is normally excellent

  • sladey66 It’s only curly at the front (@sladey66) reported from Camberwell, England

    Is anybody else getting no service from o2? It’s been woeful for weeks @O2

  • Brunts1980 Nickle Arse (@Brunts1980) reported from Camberwell, England

    Thought @ThreeUK were bad but @o2 may have to be even worse...

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

  • RoseHinds Rose Hinds (@RoseHinds) reported from Kensington, England

    @O2 Ah ok thank you. I’ve realised that my free trial with Calm has expired - how can I find out how much this is meant to cost? I’ve been charged twice and was not reminded that it would charge me this month please help

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • VictorJ1987 Vìncere. (@VictorJ1987) reported from Brentford, England

    Thanks @VodafoneUK for the run of 3 poor months of customer service requiring us to request for cancellation. Typical that your retention team could not even be bothered to make an effort. Go and listen to the phone call. I guess @EE or @O2 here I come. #Vodafone #Dontbother

  • RoseHinds Rose Hinds (@RoseHinds) reported from Kensington, England

    @O2 hi I’ve been charged extra this month for my phone / Apple Watch bill. Please could someone help me and explain why / resolve the issue

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • Si11y3gg Pawlie (@Si11y3gg) reported from Richmond, England

    @VixSeaman @EE @O2 I’m with o2 also! Was with Three before, but would never bother with EE. I will only do sim only.

  • J5752x Jay S. (@J5752x) reported from Paddington, England

    Went to @O2 #TCR to swap my monthly contract onto a prepaid card. I was told it has to be done over the phone and they can’t issue a new SIM in store. Went to @EE and asked if I could transfer my number to them. The seem enthusiastic

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • markh4780 Mark Harris (@markh4780) reported from Kensington, England

    @O2 looks like it’s gone down in London!!!! Any update on this would be helpful 🤷🏽

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • 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?

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • martinkay11 Martin Kay (@martinkay11) reported from Wandsworth, England

    Did @O2 iphone recycle thing (diff login to normal O2... would help if they told you 🙄), was quoted £132. Then get message they’ve revised value to £28. 79% reduction. Zero explanation as to why. I’ll have that phone back then #o2recycle All a bit #GreedierO2 than #GreenerO2

    @O2 I never win anything normally on o2 I have won 8 cans of Guinness in the past few days

  • nikkief8 nikkief (@nikkief8) reported

    @O2 I’ve tried webchat as per your complaints procedure and asked how to make a complaint, they have ignored that and not answered my query.

  • LAMaingi L Maingi (@LAMaingi) reported

    @O2, I spent 2hrs on the phone to customer services yday, passed on from dept to dept & spoke to about 10 people in total. No resolve, no solution, just incredibly poor customer service!... very disappointing! Ready for my next call now, but that will be to cancel my contract 😒

  • ItsJamieIRL ItsJamieIRL (@ItsJamieIRL) reported

    @O2 What’s with the 4G Issues at the moment? As soon as leave the house and go onto the mobile network nothing works. I can have full 4G and full signal but nothing is working and it’s starting to annoy me. I can’t use something I’m paying for.

  • elizabethlowson Elizabeth Lowson (@elizabethlowson) reported

    @EdwardBGreen @O2 Last year I removed daytime calling plan from landline, thinking landline would be incoming only, and I'd only make outgoing calls from mobile. Then I moved to S Woodford, where signal is really poor. I've missed calls about Last Rites - thankfully they reached me another way.

  • elizabethlowson Elizabeth Lowson (@elizabethlowson) reported

    @hermit_of_alba @O2 Landline is with BT. Do BT use their own mobile network? I'm somewhat astonished that signal is so poor here in this part of London of all places but apparently not uncommon.

  • elizabethlowson Elizabeth Lowson (@elizabethlowson) reported

    @O2 Thankyou. I've been in touch with you several times and I'm told work to improve the signal locally in E18 will be completed by the end of June. Wifi calling unfortunately isn't available on my device.

  • TyshasTweetsxo Tysha Sorai ♥ (@TyshasTweetsxo) reported

    @O2 Day 4 and I ain’t won a damn thing doubt I will tomorrow either

  • ItsJamieIRL ItsJamieIRL (@ItsJamieIRL) reported
