  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    There is always some kind of problem with my @O2 order. Its even more frustrating seeing on here people have just walked into the store and been able to collect the phone without the relevant email saying its ready to collect. How do they know they are distributing the right

  • paigebuckingham Paige🧚🏻‍♀️🌸 (@paigebuckingham) reported from Cardiff, Wales

    Anyone else on @O2 and get literally no signal? I’ve had my baby’s doctor and hospital ring me many occasions and can’t get through to me!

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Panteg, Wales

    Currently with @EE with no/very low signal at home address! Who wants to send me sim cards so I can see what network to change to! @O2 @o2 @ThreeUKSupport @VodafoneUK @ThreeUK

  • HywelButcher Hywel Butcher (@HywelButcher) reported from Cardiff, Wales

    Top tip - don’t join @O2 - incompetent and useless! First no 4G, now no signal or data at all 🤯

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service are an absolute joke - can’t wait to change my provider #pathetic

  • bethanjane22 Beth (@bethanjane22) reported from Cardiff, Wales

    When I renew, @virginmedia offer free AirPods with some plans and @O2 do the same! So much for customer loyalty, they just want more and more money! 🤬

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia @O2 Good luck to you and don't take any sh*t, you should be fully compensated for the absolute inconvenience. We had a little problem with our provider and they where excellent, understood the issue and before we asked they compensated us.

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Pontnewydd, Wales

    @SkyHelpTeam @O2 why is the network signal so poor/non existant in Cwmbran NP44

  • Waldron_Diana Diana Waldron (@Waldron_Diana) reported from Cardiff, Wales

    @O2 can u please help. I have been trying to pay my final bill with you for ages. It’s only about £20,I don’t need harrazing letters&emails to prompt me to pay...I just need u to let me pay. I have called&been online to make payment, but you don’t seem to want to take my payment

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

  • AdamLee2011 Adam Lee (@AdamLee2011) reported from Newport, Wales

    @O2 Already with o2 for my mobile and they are brilliant. This was for MiFi, someone recommended three but the signal is terrible. Waste of money.

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia I feel for you, if @O2 and @virginmedia do merge, I'm leaving at the earliest opportunity. @virginmedia leave me a little cold and with no confidence as a customer.

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service is the worst - transferring me to the sales team knowing they’re closed to fix an error that’s theirs. Can’t wait to change providers - pathetic

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    Also when I highlighted my issues over the phone and through the Webchat @O2 do not seem very concerned or understanding 😔

  • ieuanbeal15 Ieuan-Rhys Beal (@ieuanbeal15) reported from Cardiff, Wales

    @O2 your live chat service is garbage. 15

  • LisardoVivas Lisardo Vivas (@LisardoVivas) reported from Cardiff, Wales

    @O2 @tig1985 I’m in cardiff with same issue

  • BCFCOLIVERDOG Oliver City Dog (@BCFCOLIVERDOG) reported from Cardiff, Wales

    @JoeSims10 @O2 Look forward to no signal on the Portway Joe 🙃

  • flowersshanice S H A N I C E (@flowersshanice) reported from Cardiff, Wales

    Hi @O2 I’m in desperate need for someone to active my new sim (had an upgrade) as I’m unable to text or call out viseversa. My o2 isn’t solving the issue either.

  • StephenADwyer The Dwyer Identify (F) (@StephenADwyer) reported from Caerleon, Wales

    @O2 No signal for two , now on the third day , all your help lines etc are busy , no support or help , not the best customer service but you will still take my money , not impressed at all

  • andrewhillandCo andrew hill (@andrewhillandCo) reported from Abercynon, Wales

    @O2 @JohnnyMercerUK bit late that isn’t it - I think he has just a few followers who may have seen this and your ‘standard good customer response’

  • Louise63544316 Louise (@Louise63544316) reported

    @O2 awful service, take out a phone and contract then cancel it the saw day I received the phone, sent the phone back all confirmed. Then receive threatening emails and texts saying I owe them money!! I didn't even activate the phone!!!! If this goes against my credit

  • IITR07II 💪🐸👍 (@IITR07II) reported

    @O2 Recently even though it appears I have full signal, I can't use the Internet etc. (Mainly seen this when connected to 5G)

  • sasathaz Sallie Taylor (@sasathaz) reported

    Come on @Vodaphone no signal from mobile mast in Southleigh woods since last Friday. Affected most of Crockerton village and no response to reported issues. Neighbours using @EE @O2 etc also affected.

  • Sadlybrokeboy Matt Morris (@Sadlybrokeboy) reported

    @O2 just had the text about the prices rises and I have to say that’s a disgrace, to have one increase of 3.9% is bad, but yes it’s contractual but to chuck the rpi of just shy of 8% smacks of digging the arm in and taking advantage. Poor form and it will be remembered!

  • AdzCrawford2003 Adam Crawford (@AdzCrawford2003) reported

    @O2 Ok. But that was mainly for the old terms where there was no upper limit on data. Now, 25GB is the fair use and this should be at full speed with no restrictions as there’s no way of abusing the service. It is unfair.

  • journeytom T O M ✈ (@journeytom) reported

    @weste4 @O2 Part of the problem is enough people don't take action with their feet so to speak and just stay as customer

  • Heretoanywhere Kyle & Evie 💙 - 🤔 each day's a gift, not a given (@Heretoanywhere) reported

    @Hpsaucy515 @virginmedia @O2 & note that they never give any other reason than the RPI! All of the phone companies do it, it's a cartel in effect! They'll never admit it! That's why they love to make you but ones in contract! You'll pay a fortune! My phone was £450 brand new, from Google! ...

  • DamienHoneyford Damien Honeyford (@DamienHoneyford) reported

    Hi @O2, I got my new SIM yesterday but had issues activating it, though it seemed to work. This morning it's showing no service and my old SIM is still active. I called support yesterday but the operator said they were having issues and then hung up. So far, I'm not impressed

  • Heretoanywhere Kyle & Evie 💙 - 🤔 each day's a gift, not a given (@Heretoanywhere) reported

    @Hpsaucy515 @virginmedia @O2 They take us for mugs! Btw, on the signal issue, the village signal is practically non existent! At home ALL calls are automatic WiFi, the phone does that, not O2. Engineer: they must install a new tower. I'm told they refused, outright! (We weren't worth it!) Got my own back!

  • ViewAspect_ Aspect ⚫️⚪️⚫️⚪️ | NUFC (@ViewAspect_) reported

    @O2 @SophieLouiseGxo TBF this is rather shocking! Exactly why I left @O2 and went else where. Never had an issue since!
