  • 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 👏.

  • 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

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • 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.

  • 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

  • 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

  • Pretty_Gorge A dollop of kindness (@Pretty_Gorge) reported from London Colney, England

  • 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

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

    @O2 Ok, I cannot check service when I’m driving, A5 and M42 are main roads, similar places every time, surely you know where your own network is poor and what are you doing to address it?

  • Dave_Consultant David Morgan (@Dave_Consultant) reported

    @TelefonicaUK @O2 25 minutes on chat, 4 minutes on telephone tree options, 6 minutes on voice call to be transferred to a "Sales" option which wont take 1 for sales or 2 for anything else option. Had to hang up - #badcustomerservice

  • sl0wrush liv (@sl0wrush) reported

  • joannalicious Joanne (@joannalicious) reported

    @O2 Whats with the horrific signal service? I've had zero data where I live and can no longer make calls!!! Its been going on for MONTHS!

  • lswilson80 Lindsay Wilson Jones (@lswilson80) reported

    @StompTheBean @O2 I’ve been having the same issue since Friday, just been told by @O2 customer services that this won’t be fixed until Tuesday. Not good enough

  • mbrownphotouk Martin Brown (@mbrownphotouk) reported

    @O2 Can you share an eta on the sim swap issue im more than 48 hours without service which is major issue especially where you need codes ect sent by sms for various accounts Customer Services said they couldnt say when but could be a few more days! Not Acceptable!

  • lswilson80 Lindsay Wilson Jones (@lswilson80) reported

    @_southhh @O2 I’ve been having the same issue since Friday, just been told by @O2 customer services that this won’t be fixed until Tuesday. Not good enough

  • _southhh Alisha Soufflé (@_southhh) reported

    @O2 I purchased a new phone, I’ve had no signal for 2 days. I went into the O2 shop who couldn’t help me and called your customer care line on a friends phone, who promised me a call back (I’m not sure how, I don’t have a working number) - can someone help me?

  • NMatinier Nicolas Matinier (@NMatinier) reported

    @O2 @_southhh Same here. I'm experiencing the same issue, haven't had signal for days now. Because its my main number, I am now locked out of many things requiring security checks (bank etc...) via sms. The fact that you are not even willing to give a ETA is crazy. This is totally unacceptable

  • PoppyDoran4 Poppy Doran (@PoppyDoran4) reported

    @O2 hi your Regent’s Park open air theatre code does not work at checkout, please help!
