    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • 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

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • cove123 mark nicolson (@cove123) reported from Welwyn Garden City, England

    @O2 opened app to use bacon sandwich offer local greggs not open yet for some reason @GreggsOfficial Wgc poor

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    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 👏.

  • shazzstevo Sharon Stephenson (@shazzstevo) reported from Enfield Lock, England

    @O2 My calls keeps dropping. This has been happening for several days now. This is really poor service. This is in the Enfield area

  • gadgetgem Gem (@gadgetgem) reported from Barnet, England

    Missed out on my free sandwich this week @GreggsOfficial with @o2 due to the scanner being broken again. Went to next nearest greggs and they had no breakfast 😢 #o2priority #greggs #breakfast

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • ksjsowhat fiono (@ksjsowhat) reported from Barnet, England

    @O2 I made an order on the 27th of October and it’s still not in process, I absolutely need the phone I ordered within two weeks, could you help me please ?

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from London Colney, England

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

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    @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

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    £105.03 A MONTH AND FOR THE LAST 6 MONTHS NO NETWORK !!! @O2 DO BETTER

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • 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.

  • fierce_unicorn 🦄 (@fierce_unicorn) reported from Enfield Lock, England

    @O2 merlin pass code is not working, can you help?

  • sherlockbones27 marisa (@sherlockbones27) reported

    @LaurenJThomas93 @rickygervais @O2 No way. There has to be an issue. Or they only had two pre-sale tickets!!

  • Jimbobthon James Richards (@Jimbobthon) reported

    @O2 It's not the SIM card. I've tried an o2 PAYG SIM and had exactly the same. I get normal service in patches, so right now it's fine. If I go 1/2 a mile up the road, it's gone.

  • jodielouiseart Jodie (@jodielouiseart) reported

    @mckeown_ryan @O2 Worst company ever 😩 I’ve had the same from them before

  • davegriffin1233 David Griffin (@davegriffin1233) reported from Norwich, England

    @jodielouiseart @O2 That is correct and I’ve knocked them ever since I still get the internet at home and around where WiFi is for what was a brand new iPhone 11+ just use a cheap £10 phone on #vodaphone as you get network with no problem

  • AlexForsey Alex Forsey (@AlexForsey) reported

    @O2 I am roaming in the US currently for work with the travel bolt on and the data is completely unusable. I have a colleague with me from another UK network roaming on the same network with no issues. Why is this happening? The speeds involved are so slow.

  • Argyll68 Seánybhoy 😷 (@Argyll68) reported

    Moved from @VodafoneUK to @O2 in April. Worst move ever. Dropped calls every day and texts not being sent. Then after months of phonecalls they inform me they've had problems with my local signal mast! Back with Vodafone. I should have never moved.

  • Walayat_Family Dr Serac Engerraund (@Walayat_Family) reported

    O2 very weak mobile signal in Sheffield S11 now for over 1 week, cannot use phone in doors, only out doors. Come on fix it, else move to another provider. @O2 #o2v

  • TinkMissy Missy Tink (@TinkMissy) reported

    @Jimbobthon @O2 I have the same issue but with data. Can’t use internet, been trying to sort it since august. Count your self lucky you got a reply from them.

  • asimmuhammad Asim Muhammad (@asimmuhammad) reported
