  • 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 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

  • 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

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @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

  • 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.

  • 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

  • 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

  • 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.

  • 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

  • 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.

  • 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

  • MarkstanYoutube Mark Stanford (@MarkstanYoutube) reported from Luton, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • 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!

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

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • BigPhil34126382 Big Phil (@BigPhil34126382) reported

    @O2 the signal in the CH5 area has been terrible for days. Your status checker says that it's fine. It really isn't. 0 bars mostly. Other people are having the same problem.

  • AndrewNunn51 Andrew 🇬🇧£ (@AndrewNunn51) reported

    @virginmedia @O2 and @libertyglobal what are you letting your associate companies do acting in this way. Nasty business practices of the lowest form. It should be elegant. Treat loyalty as a positive and it will benefit the supplier and people will stick with you. Not bad mouth you.

  • Jermaine_ManUtd Jαу (@Jermaine_ManUtd) reported

    @O2 @BrianCo48405777 ow is a week an acceptable time to be ignored without any support? I still haven’t received the DM you said I would receive ASAP days ago

  • David_Myint David Myint (@David_Myint) reported

    @O2 been in the USA since Saturday night. Have had no roaming data since I arrived. Been chatting to your support service since I arrived and all I can say is they have been useless. Applying service and can’t believe how bad your product is.

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @alex_sutton85 @O2 I have that issue sometimes when in a 5G area. The network is clogged up. It’s literally unable to serve all the devices at peak times. If your unhappy about the situation the maybe Retweet using BBCWatchdog, WhichUK, Ofcom, Martin Lewis tags.

  • FionaTyler10 Fiona Tyler (@FionaTyler10) reported

    @O2 I've not been able to use my data for 3 days. I've been to Derby, Sheffield and close to Worksop. The only explanation I've found is a mast down in my area. I'm curious how large my area actually is now. Unable to find any other way of contacting O2 without writing a letter.

  • SparklyG Auntie of swans 🦢🚲🇬🇧🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦 (@SparklyG) reported

    @O2 Stupidly, I took out a great deal on the spur of the moment but then remembered that I don't actually get any signal where I live.

  • LoulouflyLouisa Louisa Lawrence (@LoulouflyLouisa) reported

    @O2 I put the code in but I put the wrong email so it never sent me an email

  • Jermaine_ManUtd Jαу (@Jermaine_ManUtd) reported

    @O2 @Staceygarland90 ow is a week an acceptable time to be ignored without any support? I still haven’t received the DM you said I would receive ASAP days ago

  • rachellk_x rachel keane (@rachellk_x) reported

    @O2 continuously shocking signal every call I make cuts out without fail. Barely managing 2 bars and I’m in London will definitely be looking for a new provider!
