    @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 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

  • 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.

  • 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!

  • 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

  • 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

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • 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?

  • 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

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

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • 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 Issues Reports

Latest outage, problems and issue reports in social media:

  • estellekokot Estelle Kokot (@estellekokot) reported

    @virginmedia @TheBHF @O2 At least once a day, sometimes more, my internet drops out and I lose work. Work is money so I lose money too. Then I receive an email saying that despite your contractual obligations you are increasing your prices from April + £6. Terrible service for loyal customers I’d say.

  • sabz333 sister_saber (@sabz333) reported

    @O2 my o2 priority (via virgin bb) has become linked to my sons without explanation. My son recently took out his own virgin bb (separate address) and he is entitled to o2 priority too but each time I use a priority code his comes up as used. Please help.

  • winterangeI J (@winterangeI) reported

    How can @o2 mess up so badly that my new phone gets my mums texts and my calls and my old phone gets my mums calls and my texts and my mums phone gets wiped? How the hell do I even sort this **** out?

  • hannah25959597 hannah (@hannah25959597) reported

    @O2 disgusted that one of your team members has taken a contract out with my Dads name without even his consent and then to make it worse, it is being delivered to a flat in London??? This fraud issue you have is appalling and we will be changing networks after this stress

  • kingseatchris Chris🏋️‍♂️💪 (@kingseatchris) reported

    @O2 trying to get support on your app all week but you’re always busy! My bill is wrong and I asked for a copy of my contract a week ago and still waiting

  • StrngeVnDoom Oliver Hall (@StrngeVnDoom) reported

    @O2 trying to report my Dads phone stolen after a burglary and put through to somebody to help. Only to be met with the sound of somebody snoring?!

  • chris_roarty Chris Roarty (@chris_roarty) reported

    @O2 noticed over the past year or so that this service has gone extremely downhill. Can’t get a signal anywhere anymore, calls drop out all of the time. So disappointing considering I’ve been a customer for almost 15 years! Thought upgrading my phone would sort it, just worse.

  • CaseeyCulleen CaseyCullen (@CaseeyCulleen) reported

    Proper pissed off as I bought post malone tickets on o2 priority and they were so high up for £90 each (all I could get) I look at another date for the day after tickets for close view are the same price!!! Wtf?! @O2music @o2

  • rudybanjo Rudy Banjo (@rudybanjo) reported

    @O2 Hi, been on the phone over an hour trying to cancel my contract with o2, no answer. Not the greatest business plan or PR , to trap your customers on the phone for over an hour hoping they'll give up. No online option either. Dreadful service

  • fabnewlous Sarah Bolitho (@fabnewlous) reported

    @O2 your customer service is shocking. I’ve been given wrong information about switching a number from business to pay monthly. Been disconnected three times now and have no service. What on earth am I supposed to do. I was told to call and it would be easily done. Nope.
