  • 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.

  • 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

  • BecOz14 Bec Osborne (@BecOz14) reported from Camberley, England

    Have had 1 bar of @O2 signal for most of this year, funnily enough when I tested the signal strength back in July the signal jumped to a MEGA 2 bars momentarily. #NoServiceHere

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

  • daktadre Dré (@daktadre) reported from Spelthorne District, England

    Is anyone else experiencing call drop outs and freezes on #iPhone11ProMax I have cleared cache and done soft reset, also had a sim swap @O2 but still having buggy experiencing overheating. I’ve checked online and have reset my network settings. Minded to pop into @Apple

  • 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

  • LyndallAnn Lyndall (@LyndallAnn) reported from Hounslow, England

    @O2 This issue started a few weeks ago for me and my friend has had the same issue so changed phone companies a couple months ago.

  • JoMeeres Jo Meeres (@JoMeeres) reported from High Wycombe, England

    @lollylaura40 @samantha00861 @O2 Hi, I have same problem sky seem to have the best deal, I really don’t want to leave o2 but I can’t justify paying over £56 a month when sky will do the same for £49 and you can get money back with topcashback

  • Stefan_baisden Delboybaisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    5th day in a row I've had no signal or data through to my phone. @O2 is going downhill. Definately on its way out. This is so poor I shouldav stayed with T Mobile. #O2 #POORCUSTOMERSERVICE

  • Stefan_baisden Delboybaisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 has GENUINELY the worst Phone line #Customerservice system ever. I've never been more infuriated just waiting to give a password or speak to someone. Please #O2 update your system to 2019 standard asap.

  • 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

  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • Nick_G6 N I C K 🇿🇼 (@Nick_G6) reported from Hounslow, England

    Dear @o2 and @StarlingBank it’s been two weeks and I still can’t believe that I cannot pay my phone bill via the app! Please send help I’m all out of options here. Now I’m accumulating charges for late payment 🤬🤬🤬

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @cleggytaxi @O2 Yep you’re right. Signal dropped again.

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • 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

  • LisaCoulam Lisa Coulam (@LisaCoulam) reported

    @O2 Ok, thanks for that, I think an over zealous virgin media customer service agent is more confused, or lying 🤔🤔

  • andyrennie Andy Rennie (@andyrennie) reported

    Glad I can rely on @O2 for a decent reliable 4G phone signal at my home location…….NOT ! Going on for too long now and an offer of a £10 sweetener doesnt cover it

  • martincottle Martin Cottle (@martincottle) reported

    @O2 for the love of God, will you talentless fuckeyed cockhounds please, PLEASE, provide me with a semblance of signal anywhere, ANYWHERE, within a billion kilometres of my house, or indeed anywhere on planet earth.

  • _ashbl0nde_ Karen (@_ashbl0nde_) reported

    @O2 I have swapped my giffgaff sim to o2 I have my pac no but the giffgaff sim has cancelled but no service on my o2 sim. How long will this take as I can’t be without a phone I am a carer?

  • karunshrestha3 karun shrestha (@karunshrestha3) reported

    @O2 joined last Friday, my number was swapped yesterday. Today no signal all day. I couldn’t make call, text or internet. What a terrible service. Wish I never left EE. Missed so many important calls. You don’t have any customer service on phone?? Only available in chat WTF???

  • PhilipFOTBOT Philip Smith (@PhilipFOTBOT) reported

    I have explained to @O2 three times that I have never been to Jamaica. Why is that so hard to grasp?

  • fearlessgalxo GABS (NOT MET TAY YET) ✨ (@fearlessgalxo) reported

    @O2 Hi! I upgraded my phone and I have not received an email or text to say that it ready for collection? Is there anyone able to help me update on this? My tariff has changed already but yet still haven’t received my new device.

  • LoulouKite Marie Helene Kite (@LoulouKite) reported

    @O2 We have been referred BACK to the shop in Southampton to raise an issue we are trying to sort for 2 weeks now. We were told that the shop manager has full authority to write off the bill we are refusing to pay because the terms of the contract was misleading.

  • rachee_ka Rachel Eden (@rachee_ka) reported

    @O2 Hi, I'm out of contract and looking to cancel, is calling 202 the only way I can do this

  • Dannywillo18 Danny Williams (@Dannywillo18) reported

    @O2 is the any way of speaking to a human being face to face about an issue? I’ve been the shop and they just ring a call centre for me and after 45 mins they cut me off, i ring from my own phone and they cut me off!! Worst customer service ever
