  • 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

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • Henry_Coates Henry Coates (@Henry_Coates) reported from Walthamstow, England

    @jimsmallman @O2 I left them a few years ago because the customer service is god awful! @ThreeUK is the best bet for the amount we travel! Not the best in London but all over the world it’s great

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • stourdave Dave (@stourdave) reported from Tottenham, England

    @O2 Yes #stop please **** off with this shit. I only accidentally liked your ad while I was scrolling and you've bombarded me ever since. Your signal is shit anyway.

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @JayTaylor_93 @O2 I literally get two bars everywhere. It’s so bad. Really disappointed

  • Rafacscb Rafaela (@Rafacscb) reported

    @O2 Have tried the steps and still not working. Anything else I can do to help? Can you please check at your end?

  • _JXLO_ Babu Frik (@_JXLO_) reported

    @O2 really are the worst provider out there. 2 bars of 4g maximum wherever you go never full signal and barely works, 5G can have full bars and won’t even load 5 minutes if a podcast and then you can’t even make a phone call if you have full 3G. Can we actually use our data?

  • electro_ellie Eleanor (@electro_ellie) reported

    @O2 Love that little guy! Tried those steps and not really made much of a difference, although I did find there is an issue with a mast in the area, do you know on average how long it might take to get that fixed?

  • yayoben Ben ✨ (@yayoben) reported

    @O2 Hi, data has been awful lately at and around GL15 area. 3G doesn’t work at all around here and I have to turn 5G off in settings to get 4G to work most of the time (even in non 5G areas), are there any known issues?

  • AbdalAhmed01 Abdal Ahmed (@AbdalAhmed01) reported

    The level of service recieved from @O2 over the last month can only be described as SHAMBLES! Failur after failure on their own policy and more than 3 weeks for a call back but nothing.... and they call their customer service! @Ofcom @TheO2

  • ClairEar1273 ᑕᒪᗩIᖇᗴ 🇺🇦💙💛 (@ClairEar1273) reported

    @O2 Can you tell my why my signal seems to have got so poor at my home and work place? It used to get full signal but now I barely get 1 bar somedays it seems to have been since 5g has been switched on in my area?

  • staceybwfc 🖤 𝕊𝕥𝕒𝕔𝕖𝕪 𝔹𝕒𝕝𝕝 🖤 (@staceybwfc) reported

    @O2 Hi. Are there any service issues in M28 area? Signal has been really low since Tuesday evening and data service is virtually non existent!

  • CheL1027 Chez (@CheL1027) reported

    @EE really poor service in store from you when I’m looking to upgrade. No interest in retaining me as a customer, even though I’ve been with you for years. Looks like I’ll be switching to @O2

  • Dan12776326 Dan (@Dan12776326) reported

    @SidAhme67642789 @O2 Thanks. Did they rectify this issue? I moved over to O2 because I was travelling to Canada!

  • ho_sewa dipak Mainali (@ho_sewa) reported

    @nothing @O2 I have started using this phone for 7 days, all the features are fine, but the phone is getting hotter, I can't use it for 30 minutes. What is the solution? Please reply. Thank you.
