    @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

  • 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

  • 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?

  • 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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • 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.

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • realirish The Irish starvation (@realirish) reported

    @O2 Your network in Derry no longer has enough data bandwidth for users. No delivery of a new sim card either.

  • grshorwich Godwin Stewart (@grshorwich) reported from Lea Town, England

    @psychomania666 @O2 And of course on 3G you do get a reasonable signal but no actual data throughput...

  • KINGFATY45 King Faty (@KINGFATY45) reported

    @O2 can you help me with a stac code please

  • robbo_jonny Jonny Robbo (@robbo_jonny) reported

    @O2 impossible to contact a communications company without waiting for years on the phone. Why do you not have an email address for customer service?

  • RichardHofman33 Richard Hofman (@RichardHofman33) reported

    @O2 Hello, please because there is no more chat support on the O2 website to get information, so I'm using the opportunity to ask O2 this way. Please, I want to get PAC code but it's not coming the way you have shown on the web. I don't want to leave O2 but only get the PAC code.

  • Richardisbanned Richard (@Richardisbanned) reported

    @O2 why is my internet permanently shite why do I pay for a service I don’t get

  • EmathsUK Mark McCourt (@EmathsUK) reported

    @O2 No matter how many times I convince myself that your customer service can get no worse, you once again prove me wrong. If you're going to save money by forcing your call centre staff to work from home, perhaps give them systems that don't hang up on customers mid call.

  • JvonJvon Jvon udine (@JvonJvon) reported

    @O2 I cancelled my contract and said I wanted to keep my phone as pay as you go which the guy said he would send another sim to do the exchange and I never got the sim and till date nothing I called now for a puk code only to be told I can’t get one cause my contract is cancelled

  • seanohalloran seanohalloran (@seanohalloran) reported

    @O2 simply the worst customer experience. Been trying to give you money for an upgrade since 9.30 am. Every customer touchpoint is broken. Payments, MyO2, update my details, customer service, chat, phone menus - everything!! ******* shambles. Any other networks want my business?

  • Kerryannemills Kerry Mills (@Kerryannemills) reported

    @O2 - def the worst customer service ever. 3 hrs of my life and then get cut off🤯 Please sort out your phone lines 🤬
