    @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

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

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

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

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

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • 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

  • 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.

  • 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.

  • 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. 👌👌👌

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @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?

  • 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.

  • 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

  • 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

  • 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!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

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

  • Silvia26p Silvia (@Silvia26p) reported

    How do you get a new contract with @O2 ??? 35mins on the phone pressing 1 for sales over and over. Yesterday same 25mins and gave up. Awful service!! @O2 Don't you want new customers???

  • Pat__Turner Pat Turner 🎗️ (@Pat__Turner) reported

    @O2 your customer processes and services are appalling. Every time i fill in the form to port my old number it errors out. Your live chat is permanently busy. Call waiting over an hour. Earliest call back option is 28th Jan. What a joke

  • buntyshah007 Bunty Shah (@buntyshah007) reported

    @O2 saying the code is invalid - help!

  • trigmk2 Alex (@trigmk2) reported

    @O2 I've been on the phone for 1.5hrs, bounced around depts trying to return a faulty S21 handset within 30 days to be told you no longer stock it. I can have a previously returned handset, or cancel my contract & take out a new, more expensive contract, on an inferior handset.

  • EllyEllygoodman Elly Goodman (@EllyEllygoodman) reported

    @O2 o2 you are the worst provider I’ve ever come across we have been treated appallingly and no one seems to care or provide us with a solution - im beyond furious

  • Fraggle05 Fraggle (@Fraggle05) reported

    @O2 I would like your CEOs contact details as frankly your customer service is appalling. 5 weeks I have been attempting to sort an issue with your company and it has now resulted in you taking £200 out of my bank account incorrectly and refusing to refund it for over 3 weeks.

  • Sri2Sree2 S r e e (@Sri2Sree2) reported

    @O2 But how is that going to help??? Do you guys even act on them n catch them and take necessary actions??

  • craigypickle craig (@craigypickle) reported

    @O2 hi, if I was to take out an o2 sim only contract via uswitch, can I transfer my current number from my previous network?
