  • 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?

  • 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.

  • 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

  • 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

  • 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

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

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • 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!

  • 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

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

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • 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.

    @O2 my sim has been blocked by accident and I need a PUK code. Please can you help without having to spend hours on hold?

  • exRVN4240 4240Bex 🐜 |🏹🍸 (@exRVN4240) reported

    @thedogman_918 @ThreeUK @O2 Bad isn't it. Had been with Orange (now EE) years, asked if they could offer me a better deal as I may need to move to another company if not, they just said 'oh ok, fair enough'!!

  • Sarj007 Sarj Mistry (@Sarj007) reported

    As far as #CustomerService goes @O2 have to to be the absolute worst I have ever seen Believe me, I've worked in customer services for 25+ years It's beyond shambles A bunch of absolutely incompetent people, every single one of them

  • millypeckam Samantha Finch (@millypeckam) reported

    @virginmedia @TheBHF @O2 Who in your company listens; been trying to resolve a problem since beginning of December and all you keep doing is sending threatening letters EVEN THOUGH WE ARE NOT CUSTOMERS OF YOURS!!!

  • Denirogers DENI ROGERS 🇬🇧 🇺🇦 🇪🇺 (@Denirogers) reported

    @thedogman_918 @ThreeUK @O2 You’re well out Chris, one of the few companies charging roaming again. They’ve let me down twice now when I was abroad. I’ll change when my contract comes up.

  • EandAG evergreen (@EandAG) reported

    @thedogman_918 @ThreeUK @O2 I went to 3 to talk about an upgrade recently. The salesperson was more interested in trying to get MrG to move contract from another supplier. MrG politely told the salesperson to speak to me (their customer) first but after still trying a few minutes later we walked out.

  • thedogman_918 Chris Green (@thedogman_918) reported

    @olisquiress @ThreeUK @O2 I'm the opposite, virtually no signal with 3 where I work.

  • Jeffmw1 Jeff Wheeleree (@Jeffmw1) reported

    O2 phone and text service has been shocking in my area (GU35 8..) for last couple weeks. Apparently faulty mast. Lots of local folks complaining on FB, WA and Twitter. How long does it take @O2 ?

  • ClaireLBrennan Claire Brennan (@ClaireLBrennan) reported

    @O2 None of those are working. There isn’t a fault in my area. Is there a way of speaking to someone about this that doesn’t involve logging into my app. As I said, it’s asking for a code I can’t receive without signal

  • Ayyyzmah ayyyzma (@Ayyyzmah) reported

    Literally fuming with @O2 customer care and service to the point it warrants a formal complain. How waste of space can a service be?!
