  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • 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

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • paul_a_lewis Paul Lewis (@paul_a_lewis) reported from Barnet, England

    @O2 my wife joined O2 today and ordered a new phone however she provided you with the wrong email address, can you help change it? Thnx

  • 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!

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

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

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • 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.

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Fixed the issue. Turned Volte off, rebooted, turned back on and got wifi calling back :)

  • ProfLisaDowning Lisa Downing (@ProfLisaDowning) reported

    @O2 every time I call your customer service number: "It has not been possible to connect this call". How is this acceptable? Please contact me. Terrible service.

  • SJ_OXO SJ. (@SJ_OXO) reported

    @O2 guys I haven’t had network since Monday and now it’s now Friday and it’s still down. My kids school can’t even contact me if somethings wrong this isn’t good enough!

  • Briareos35 Steve Collins (@Briareos35) reported

    @O2 @dazyoungs @EE Ha! Just read the previous DM's I've had to send you! Now signal has dropped in my house inexplicably over the last few months and I can barely make phone calls and be understood by the person on the other end! Sick of it, stupid poxy 36 month contracts as well absolute farce.

  • Scottroyb1 🐏 Scott 1 🐏 (@Scottroyb1) reported

    @O2 your customer service is a joke. Been lied to every day for 4 days running now. #getinthebin

  • josskorvus Joss Korvus (@josskorvus) reported

    @O2 trying to cancel pay monthly data sim. No cancel form logged in to www. Cannot call 202 with sim in phone, calling fails, data works. Call landline and it cuts out after 10-20 mins. Please help

  • jordan_dilks Jordan Dilks (@jordan_dilks) reported

    @O2 Yes says there’s nothing wrong with my network either so I’m a bit confused

  • Jamesba66061676 James baxter (@Jamesba66061676) reported

    @O2 Most companies are using Covid to reduce support staff and let the ques build up. 02 for instance seem to always have 30 min wait time, knowing no one will wait 30 mins then palm you off with a CRM system, that doesn't even get close to addressing the problem

  • PaulgPowell Paul Powell (@PaulgPowell) reported

    @MichaelBratley @O2 I've had the same issue and still no fix date 😡

  • razorrahman Shafer It Rahman (@razorrahman) reported

    @O2 Just took out contract 5 days ago and not getting network coverage

  • Jamesba66061676 James baxter (@Jamesba66061676) reported

    @O2 In my situation all my calls are going to the voicemail and there is no way I can get support from customer services. Shocking, no wonder why customers are switching between telecos
