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

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 There’s delay then there’s rude. Been 92 working days or 128 days since I complained. @o2 are making it deliberately difficult to contact.

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    Hi @O2 as you’re aware I’ve been on no service now for over 3 weeks, any updates yet or? Or do I just continue to pay £60 a month for a phone I can’t use unless I leave my house ?? If someone with a brain cell can get in contact that would be fab 👍🏻

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    Hi @O2. If you received a notification that a sound was played from my phone, please don’t worry. I was just testing out the Find My app on my iPhone, as I’ve never used it before, so I just wanted to check it out and see how it worked. Thank you and sorry. :)

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    What is the point of complaining to @o2? Complaint sent 06/09 multiple times chased up formally 20/11 no reply now 06/0/21. Told someone looking at as a priority still nothing @MarkEvansO2

  • BristolOli Bristol Oli (@BristolOli) reported from Cardiff, Wales

    @BS3Rob @O2 @WBA Been horrendous for weeks - Can’t complete a call without having to call back numerous times - BS3 probably the worst of them all but M4 corridor from Cardiff to Bristol is a close second

  • nopantsuk Nick Thorogood (@nopantsuk) reported from Llanharan, Wales

    @O2 my number should be ported to you today that I requested yesterday morning. I’ve had no confirmation texts or emails though and number still on old network. Any ideas?

  • Garethbird85 gareth bird (@Garethbird85) reported from Newport, Wales

    @O2 can someone from customer service contact me please

  • LisaEdwards78 LisaEdwards78 (@LisaEdwards78) reported from Barry, Wales

    @O2 Hi there I have had a highly Sophisticated national insurance scam call from a number registered to your network. There was an automated message purporting to be from the national crime agency. Please can you investigate this number 07850058296

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    3rd week of no signal and @O2 in absolute NO rush to fix the issue. Can’t wait to cancel my contract this week 🥳

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

    This weather properly has me over a barrel. Mistreatment by @O2 properly has me feeling down. My #CovidVaccine pain is bad. Some days the demons are just too much to battle...but today is not one of those days. Rest, relax, refocus. #MentalHealthMatters #BipolarDisorder

  • DennerSusan susan denner (@DennerSusan) reported from Cardiff, Wales

    @O2 Customer service shocking! No service on phone since 24th May, SIX calls made to your call centre to resolve issue - now being told to wait for

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

  • PattersonLela1 Lela Patterson (@PattersonLela1) reported from Barry, Wales

    @O2 I didn’t receive an alert and neither did my family. It’s a fantastic idea, though! Are all Network operators doing this? :)

  • meribelman Peter Williams (@meribelman) reported from Penarth, Wales

    @virginmedia I would happily self serve online, via a browser or app, as you incessantly encourage me to do, but when the page says “oops something went wrong, we’re unable to change your package online”, its very frustrating. @O2 will help you soon!

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • notrowenaa i am a hater (@notrowenaa) reported

    .@O2 customer service is getting worse and worse and worse! More so, if you're doing works to the network, shouldn't you notify customers beforehand and before they lose access to their data? Not send them a text after they contact customer services? No compensation?

  • RachLloyd13 Rach (@RachLloyd13) reported

    @O2 the Apple Music offer in Priority is telling me I’m unable to redeem with my subscription. Can you help please

  • Erroden_ Roro (@Erroden_) reported

    @O2 you are the scummiest network in this country. I had fraud committed against me with two contracts placed against my name 7 months ago AGAINST MY CONSENT with your service (I HAVE NEVER USED YOUR NETWORK). I contacted your customer service as soon as I was made aware -

  • kazbaz68 Karen Wells (@kazbaz68) reported

    @O2 What reduction will I see in my 2 mobile phone bills? No service at all since Monday? It's now Thursday, and you send me a text (we have had to turn on WiFi calling to be able to receive anything, and that is patchy) to advise 'you are working on it'!

  • BcfcMaddocks Aaron (@BcfcMaddocks) reported

    @O2 #TBT to when i had signal off O2.

  • amit2766 Amit (@amit2766) reported

    @O2 Never mind I got the network. Thanks a ton.

  • Callumg00 Callum ❤️ 🍂 (@Callumg00) reported

    @O2 4 hours and still nothing, got no further, absolutely ridiculous now. How hard can it be to cancel an order? I'm £400 down, which is the deposit I paid. And I bet if I called, it would go around in circles as it has done for however long.

  • jemmaagregory Mrs Gregory (@jemmaagregory) reported

    @O2 customer service and insurance 0 stars. Customer for over 10 years and absolutely no help with my insurance claim as the phone is out of stock. Can’t even upgrade. Not good enough

  • Antoinettes15 Antoinette Smith (@Antoinettes15) reported

    @O2 hi there I’ve rang the customer service line twice today requesting an email to be sent to me. Both assistants said they had sent me this but I am yet to see any emails from o2. Can you help?

  • SineadDoyle Sinead Doyle (@SineadDoyle) reported

    Is every phone network just as bad as the next? Had terrible experiences with @O2 previously, moved to @VodafoneUK who seemed ok for the past couple of years but have been a nightmare this week. In the middle of an upgrade I’m considering cancelling but are they all the same?
