  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @teamIPSE Without a doubt! And phone signal! It is appalling how bad the signal is in parts of the UK outside of London! I am 4 minutes from the Cardiff city centre with no signal! #howareyoumeanttorunabusiness @o2networks @O2 @giffgaff

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RobBruceK @ThreeUK @O2 @EE @VodafoneUK No awful. Just spent 5 days with no data/calls due ti Insufficient bandwidth. My family and friends who were with O2/BT/Vodaphone had no problems. Worst ever. So regret leaving previous provider last month. Their coverage checker is inaccurate too

  • CJLittlemore Callum James Littlemore 🔶 (@CJLittlemore) reported from Cardiff, Wales

    @O2 I woke up this morning to find I’ve been totally cut off. I can’t make calls, send texts or use my mobile data. All of this is kinda important for my work as I’m self employed - I can’t call your customer service line to see what the issue is. Can you look into it please.

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    @jolilford @O2 Your kidding me!!! I have contacted customer services 3 or 4 times. Shocking service

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    Totally disappointed with @O2 customer service. A number transfer from a consumer account to business took 8 days when I was told it would take 24 hours. 3 phone calls to customer service and still not 100% sorted. #totallycrapexperience

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @O2 This has always been an issue. We are with giffgaff whom I believe use your signal. I have tried everything. I have even bought a booster, but the reception coming into the booster isn’t enough to even make the booster work. Very frustrating. I have to sit in a window 4 reception

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • 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! 🤬

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

    @O2 your live chat service is garbage. 15

  • 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 🤯

  • jamieriddell Jamie Riddell (@jamieriddell) reported from Cardiff, Wales

    Hey @O2 who can I talk to about unlocking a phone. I've paid up and out of contact. Online form says no because of too many attempts ( no idea what my customer service code was) but I have all my account details.

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

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

  • 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

  • daunce4thstreet Garry Dauncey (@daunce4thstreet) reported from Pontypridd, Wales

    Never use @O2 recycle! sent them a phone that was in perfect condition & now they say the phone is damaged and are offering peanuts for it. If it’s damaged blame the flimsy packaging you send.

  • 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

  • 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

  • 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

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

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

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

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

  • 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’

    @O2 still no signal , Sheffield

  • HarshaBala_ Harsha Bala (@HarshaBala_) reported

    What I’ve learned? Using #O2Travel could risk your #CreditScore & @O2 won’t fix this in a hurry, even if it is their mistake.

  • T_XIII Jag Grewal (@T_XIII) reported

    Check your bill if you took out a contract with @O2 before 25th Mar they increased by #RPI April onwards. Whilst legally correct, I would suggest you don’t change your mobile contract until after 25 March each year to avoid RPI increases. Maybe @MartinSLewis help get the word out

  • Stacie1910 StacieH. (@Stacie1910) reported

    @O2 any idea when the service will be back in the OL6 area. I've had no signal for over 24 hours, just saying 'emergency calls only'

  • neiltheshaker Neil Davis (@neiltheshaker) reported

    Blimey @O2 looks like your customer service is as impressive as your network coverage these days….

  • AJM100000 AJM70 (@AJM100000) reported

    @O2 where is my phone? Supposed to be delivered today. Says on dpd o2 requested it back?! Nice to be contacted! Awful company

  • andrew_conaboy Andrew Conaboy (@andrew_conaboy) reported

    @O2 I live in Germany, today I paid off my devices, left o2-uk, was given my PUK code, closed my o2 account and inserted my German SIM. It does NOT work. Now I have a phone which I personally own and no way of using it. I need help urgently.

  • AndrewjG79 Andrew Gardiner 🇺🇦 (@AndrewjG79) reported

    @EE Come on you can’t even make EE work in Wembley. Shite network that’s why I ditched you for @O2 they are cheaper and better in every way.

  • Ccynica Ccynical (@Ccynica) reported

    @O2 What's the point your internet is very slow

  • sosamuk sam rose (@sosamuk) reported

    @O2 All up to date, I’ve restarted the phone and it’s with all contacts and when I went into the O2 shop they said they couldn’t help and to contact you online
