  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • __luuwilliams luu (@__luuwilliams) reported

    @O2 clearly don’t want me to pay my final bill with them, have attempted to do this several times online and through the app, no longer recognises my details. Also tried ringing customer services and have been cut off every time after being put in a queue. Glad I left them now 👍🏼

  • LewisFigo8 lewis roberts (@LewisFigo8) reported

    @O2 I recently upgraded and said that I didn't want a spend cap on there but there is one. Please help.

  • jennahowardx Jenna Howard (@jennahowardx) reported

    @O2 your customer service is shocking I’d have more luck getting the Queen on the blower than you. Why is it impossible to get someone on the phone, 45 minutes of holding to be hung up on. I need assistance please!!

  • edw241 David edwards (@edw241) reported

    @O2 any chance of a phone signal Guys? No improvement round here (TA14) in a decade. Unbelievably poor…

  • ianmichell Ian Michell (@ianmichell) reported

    2/2 @O2 #o2fail - after @O2 admitted fault, being over charged and being told to claim the money back from my wife’s bank… we were then told when we wanted the PAC number, that the account would need to be reinstated and that they would then charge termination fees. WTF?

  • edw241 David edwards (@edw241) reported

    @O2 You’re missing the point, I think: it’s 2021, and we all pay a huge amount of money to your company and yet in rural areas like mine signal is terrible. Nowadays this is a basic necessity and your company needs to ensure coverage. Simple.

  • spillanemary mary spillane (@spillanemary) reported from Wandsworth, England

    @O2 what on earth? A mast down last week. Today another bloody mast down. You’ll update me when? AUGUST 27?! time to switch

  • JamesD_1807 James D (@JamesD_1807) reported

    @UKCopHumour @GorillaoJustice @O2 Glad it's not just me, Bedfordshire, Cambridgeshire and Northamptonshire terrible. Standard of excuses of engineer aware, can't get access to mast etc. Never used to need WiFi calling outside!

  • Raveenix1 Raveenix (@Raveenix1) reported

    @O2 so it's been almost 3 months and still no fix for the H+ signal issue in Burton on Trent.... Getting ridiculous now

  • rajrobbo Raj Kaur (@rajrobbo) reported

    @O2 customer for over 20 years and customer service is shocking!! Goes with the coverage too. In a major city and can’t even can get any coverage!!
