    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • 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.

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • 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

  • 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 👏.

  • 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.

  • 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

  • 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

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

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • 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

  • 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!

  • x_mrsdaws_x Nataleah Daws (@x_mrsdaws_x) reported

    @O2 mine and my husbands airplan should be discounted with my blue light card discount. Last month it was £14.90 this month its £24.74. What's going on please? I can't even get on the website to check as it's down.

  • _OfficialWils Wils. (@_OfficialWils) reported

    @O2 Could you help me please, the back of my iPhone is damaged and the glass has cracked badly, I have insurance with you guys would it be possible to get it fixed please?

  • andywexford1 andywexford (@andywexford1) reported

    @O2 Been with you for years but you are downgrading my tariff so I'll pay the same and no longer get the 75 countries. Such a shame you have done this to a long standing customer, no reward for loyalty. I'm going to head off to 3. They can give me a better deal.

  • imaduahmed1 Imad Ahmed (@imaduahmed1) reported

    Glen from complaints team rude as usual. An absolute ****. @O2 can I please have someone other than that bloke call@me urgently.

  • CraigFairlie Craig Fairlie (@CraigFairlie) reported

    @O2’s network has been hellish in Perth over the past 48 hours!

  • markl70 Mark Lees (@markl70) reported

    Poor customer service @O2 . Do you want to keep customers or lose them?

  • RichJPuttick Rich Puttick🇬🇧🇪🇺 (@RichJPuttick) reported

    @ps5ukalerts Nope couldn’t verify my card because @O2 network is ******* down

  • stefspeaks Sophia Petrillo (@stefspeaks) reported

    Broadband seekers - stay far, far away from @virginmedia (subsequently @O2 now too). Never witnessed more incompetent customer service or worse internet speeds. The scum of the earth of telecom companies. They also charge you hundreds of £££ if you *gasp* decide to move house.

  • RichJPuttick Rich Puttick🇬🇧🇪🇺 (@RichJPuttick) reported

    Absolutely fuming first @verynetwork @VeryHelpers don’t call back regarding my ps5 order so i lost it again! Then i get through to order a bundle with ratchet and clank from very again and can’t verify my card because the @O2 network goes down!! ******* shambles!!

  • IxROCKAFELLAxI Alex (@IxROCKAFELLAxI) reported

    @O2 I’m used to poor signal, but this morning I have no data at all. I’m in Coventry. Weird
