    @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! 🤬

  • 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

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

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

  • 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

  • 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

  • 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

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

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

  • ThisIsDanGuy Dan Guy (@ThisIsDanGuy) reported from Cardiff, Wales

    @O2 sucks that reduced the number of cafe Nero codes 😡

  • 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

  • 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.

  • 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

  • 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’

  • 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.

  • 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

  • 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

  • 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.

  • RahmanLab Taufiq Rahman (@RahmanLab) reported

    @HyvonenGroup @O2 i have been experiencing the same issue with them for a while, Marko...so annoying!

  • Dan_Mc_Loughlin DaniMac (@Dan_Mc_Loughlin) reported

    @O2 please can you tell me how long is left on my contract? I can’t log in because the phone is for my mum so the text to the handset doesn’t help me.

  • CharlesTinworth Charles Tinworth (@CharlesTinworth) reported

    @O2 Hi guys, like many others… you continue to fail to port my number over. This has been going on since last week. I am missing all sorts of things and there appears to be no end in sight. How long can this continue?!

  • HoulihanFinn Finn Houlihan (@HoulihanFinn) reported

    @O2 please can you provide all your new O2 customers with an update on your porting issue. Save us all wasted time making pointless calls to your call centre. #help #sos

  • HoulihanFinn Finn Houlihan (@HoulihanFinn) reported

    @ElaineEdwards13 @O2 @O2 dealing with this serious issue with silence doesn’t look great, I’d expect better from a Plc ?

  • Sharp_Essential PatrizioLiam85 (@Sharp_Essential) reported

    @O2 I tried that but it happened to me when I tried to get the Odean ticket so when I looked on twitter to message 02 loads of other people was having the same problem. So refreshing it wasn’t helping it was a glitch on your side to do with the cinema tickets- it happened last week

  • coops_92 Miles Cooper (@coops_92) reported

    @O2 is there a problem with number porting? Lost service on my old sim and my current one so I’m unable to call customer services…

  • Irons_FPL StressyFPL (@Irons_FPL) reported

    @O2 Are you taking the actual piss? Many people with no phone number due to your stupid system not porting them and your tweeting this? Sort your **** out 6 days I’ve been without my number you morons

  • Simon_Telford Simon Telford (@Simon_Telford) reported

    I ported my number to @O2 on 18th October and it’s yet to be completed fully (still don’t receive texts…). FYI @Ofcom having to phone for updates every 2 days and still no real update on the issue or resolution timeframe.
