    @O2 How is that great value for a customer, when a sim only package is £30, yet its £35 when you purchase it with a phone?

  • Daniel_Lyddon
    Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    If it wasn't for all the free benefits I got with @O2 Priority, I'd ditch them. Their #CustomerService is abysmal. It's like being in some weird kind of abusive relationship: "we'll treat you like **** but give you lots of free stuff so you'll want to stay with us" 🙄😡

  • Daniel_Lyddon

    (4/4) ...as being the fault of an automated system, without any recompense or any attempt to suggest that they can improve, is horrifying. I feel almost constantly threatened, intimidated, and abused by @O2 due to an issue that they caused, and they are making no attempt to fix.

    @O2 Totally ignored my actual question, do I get a rebate on my bill if I experience technical issues?

  • Daniel_Lyddon
    Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/4) Not a week after I was horrifically abused by an @o2 #CustomerServices agent, and even after I settled the payment issue (ongoing problems with #O2 automated systems since last Aug/Sep) that very day, I have today received three consecutive threatening/#legal letters...

  • Daniel_Lyddon
    Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (2/4) ...from @o2 dated TWO DAYS after the issue was, I was told, cleared up. A call to #O2 #AccessForYou this afternoon shows the issue is cleared up and the letters are auto-generated because payments can take up to 48hrs to register with O2...

    How can @O2 sponsor the World's most popular concert venue as in @TheO2 but can't give me a decent signal for 50% of my day?

  • Shaunalj93
    Shaunalj (@Shaunalj93) reported from Ferndale, Wales

    I need some help @O2. I was told I can get o2 open as I have a @bluelightcard but when I’m trying to register it online it is not accepting my device.

  • Lea_May_
    Lea French (@Lea_May_) reported from Cardiff, Wales

    @O2 don't recommend upgrading with o2. Terrible service, can't speak to anyone on the phone and waited for over a week for my delivery that was due on Monday!

  • BigDogWrestler
    🌈 Champ (@BigDogWrestler) reported from Cwmbran Central, Wales

    @O2 why is my signal often very poor and I mean often and very very poor?

    @O2 hi, I’ve been waiting for a SIM card to be delivered for over a week, tried speaking to your support people who wanted the code they’d sent to the phone which I couldn’t give them as I don’t have the phone! So frustrating

    Shocking signal today on o2 postcode NP18 1NF @O2 @mrsclart

  • sarlpar
    Sarah (@sarlpar) reported from Henllys, Wales

    @O2 It’s been going on for months, I have friends dotted around NP44 and they all struggle making phone calls as they keep dropping out, it’s not something new it’s an ongoing issue. I’d change if I wasn’t tied in and I think you’ll find other would too if they could. So frustrating

    @jasonmackenzie @O2 OK I once had trouble with EE (not for the mobile service but when I switched to broadband), it got so bad that I decided to go back to Sky. (NB now with TalkTalk, also not great for customer service but OK if nothing goes wrong.)

    @O2 Poor customer service again!!! Can’t get hold of anyone and just going round in circles on there so called, help, pages!!!

    Dave South (@davesouthphoto) reported from Cardiff, Wales

    If I had a £1 for eveytime @O2 text me about my local mast being down. I wouldn't have to pay for my contract anymore. Wearing thin now guys.... 🙄

  • Daniel_Lyddon
    Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    30 mins on hold to @O2 customer services, spoke to an agent who has now put me on hold to speak to transfer me to #CustomerServices...so God knows who the hell I got through to 🙄😡 #FirstWorldProblems

  • sarlpar
    Sarah (@sarlpar) reported from Henllys, Wales

    @O2 your coverage in the Cwmbran area NP44 is shocking, no end of people on O2 post about the poor signal especially around the Llanyrafon and Henllys/TyCanol area. When we ask about if there are any signal issues we’re told there’s not, Vodafone, EE and 3 work prefect. 😖

    @O2 Apparently the helix case that has been sat with back office not been worked on - the complaints team have advised it will be deadlock if not actioned. They do not understand why this hasn’t been sorted and can’t provide a response to when. Disaster, 20years a customer

    @O2 Thanks - that's the one that doesn't show "My Account"! No one seems able to fix it.

    @O2 @AdamTakacs13 Adam. You have 30 days to leave O2 & move networks. You do still have to keep paying for the phone. Just get a new phone on a new network and sell your current phone and use that to pay it off. I changed last night and moved to Voda. You can take your number too.

    nicolas anderson (@nicolasanderso1) reported

    @_ItsTitch @O2 Absolute shite horse company. Customer service is shocking to say the least. And to top it all off you get scammed by one of the operators!!! That’s why I ported my numbers out and left. Got a better deal and English speaking operators

    @_ItsTitch @O2 I did this and they tried to charge me to terminate my handset instead. Clueless.

    @KatiePaine5 @O2 I got an email from them yesterday regarding this change. You can cancel your airtime within 30 days when they inform you of this change. So I called and got my PAC number. Surprisingly it took only 5 minutes to do this. You do still have to keep paying for the phone.
