    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

  • 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

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

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

  • 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 🤯

  • 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

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

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

  • 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

  • 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.

  • 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’

  • 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.

  • 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

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

    @O2 your live chat service is garbage. 15

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

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

  • 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

  • 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.

  • 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.

  • 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! 🤬

  • 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

  • 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

  • Silly_midoff Silly Mid-Off (@Silly_midoff) reported

    Hi @O2 ... your customer support voice menu maze is so inflexible and absurd it brings whole new levels of frustration to a relatively simple task- your total refusal to allow me to speak to a human even via live chat means I can’t pay you sone money you surely want from me ?

  • bohford Beau Harrington (@bohford) reported

    @O2 Hello, thanks for your reply. No VPN or anything like that, I’m afraid. I have asked a couple of acquaintances also on O2 UK and they experience the same issue.

  • AlanYoungUK Alan Young (@AlanYoungUK) reported

    @O2 General coverage just seems poor. Almost non existent at my home or workshop

  • Phaceless_Photo Phaceless Photographer® (@Phaceless_Photo) reported

    @ritamoraruk @O2 That’s probably a SIM card issue

  • NickyThomas Nicky Thomas (@NickyThomas) reported

    @O2 Despite even speaking with a customer rep on the phone, I told them what the issue was and they reassured me they would pass the message on and make sure your 'service' centre looks into it properly. Clearly, they can't read either?

  • LaurenBeckwit11 Lauren Beckwith (@LaurenBeckwit11) reported

    4 attempts for my husband to get some sense out of @O2 this morning and midway through the call that seems to be going somewhere and they’ve cut off his service! Amazing! Bye bye O2! You really are the worst.

  • DiLussoMenswear dilussoclothinguk (@DiLussoMenswear) reported

    @O2 @GreggsOfficial No thanks a working network like the others is all we want

  • James14691733 James (@James14691733) reported

    @O2 you ought to be ashamed!! 2 of your representatives phoning me and 1 was lying. Awful customer service and I will wait and get a new contract with another service!!!

  • pickled_tinker Ian Grody (@pickled_tinker) reported

    Such a shame that some customer services agents at @O2 bend over backwards and are more compassionate than the company they work for. I've had nothing but shoddy performance from this network from day 1. Your staff deserve more. Your services suck and your staff bare the brunt.

  • s_w_photograph Stuart Williamson Photography (@s_w_photograph) reported

    @O2 No problem. Hopefully nothing will happen as it was a blank screen & didn't download or enter anything
