  • 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 🤯

  • 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.

  • 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.

  • 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.

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

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

  • 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

  • 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

  • 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

  • kdhanz KD Hansford (@kdhanz) reported from Mountain Ash, Wales

    @EE I'm fed up of your network in aberdare. It hasn't worked tidy for months and I have two contracts with you. Please sort it out or I'm leaving to @VodafoneUK or @O2

  • 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

  • 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

  • Rhian1975 Rhian Langham (@Rhian1975) reported from Cardiff, Wales

    @O2 shocking attitude of customer service rep. Please get in touch.

  • 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

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

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

  • 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’

  • 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

  • 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.

  • 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

  • queen_modise Queen Modise (@queen_modise) reported

    @O2 A default has now been added to my credit file for a SIM card I requested to cancel on multiple occasions. I was told by the contact centre that the reason the phone line cuts or I am put on hold for such a long period after requesting to cancel.

  • SquireHeather Heather Squire (@SquireHeather) reported

    @O2 The mast not working in Sturminster Newton, Dorset, is causing real problems in this rural community, eg pregnant women being unable to call the midwife, people missing medical appointments. There has been no signal for 6 days already. This is urgent. @Simon4NDorset

  • Santhebeach San Taylor 💙 (@Santhebeach) reported

    @O2 hi. Need help. Just tried online to get my husband a sim only contract - he had just got his PAC- was declined. Spoke to Flowers- said because we have joint account refused?! Why? Do we need to go I to o2 shop?

  • swinter100 Scott Winter (@swinter100) reported

    Now into day 4 of no @O2 signal, no doubt next week my payment will still be going out.

  • ladytarasimone Tara Longworth (@ladytarasimone) reported

    @O2 I left o2 because customer service was shocking,you’ve sent me a final bill but I can’t view it as I can’t log into my account anymore iv been on hold for days. So I’m posting this as evidence that iv tried but how can I pay my bill?

  • dkinnear David T Kinnear (@dkinnear) reported

    @O2 I went to your FB page in desparation and sent you a request for help via Messenger since there is zero help on your primary website

  • ASwainbank Arielle Swainbank (@ASwainbank) reported

    @O2 Apparently being a loyal customer for 20years means literally nothing haha

  • chireg69 Lee Jones (@chireg69) reported

    @O2 Bollocks to you and your 17% price increase. Thieving off customers in times of trouble. In fairness though, how's anyone suppose to survive on only a few billion quid profit! Absolute scum of the earth.

  • TheYetsman Sam Barnes (@TheYetsman) reported

    @O2 why is my signal so poor, I’ve reported this a few times other the last few months, and you have assured me it will be fixed but it hasn’t, I have been sold a contract under false promises and you wanna charge me if I choose to leave

  • nicolakezia86 Nicola (@nicolakezia86) reported

    @LaurenFirth @O2 Exactly. It’s definitely not how I expect to be treated as a customer of over 15 years! Really poor.
