    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • Borehamwoodbine Woody (@Borehamwoodbine) reported from Borehamwood, England

    In over 9 years with @O2 I’ve hardly ever needed customer services help and now after 3 attempts this year with little or no help I would just like to say thanks for nothing!

  • 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

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

    @O2 Thanks guys. Going to get someone I know with O2 to come through so I can check what your network coverage is like. Wife’s with @VodafoneUK and has no issues.

  • 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.

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • lexibeqiri Lexi Beqiri (@lexibeqiri) reported from Barnet, England

    @O2 Bought a pair of airpods in september and I have problems with the right one for over a week. It is not connecting properly. What is to be done? Thanks!

  • 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?

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • 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.

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

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

    @EE following up on the bad signal in the area I now stay in, can’t even have a call while walking in the neighbourhood, I may have to make a drastic decision and move to @O2 I’m in a 12 month contract so what are the cancellation terms if you can not provide a reliable service?

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

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

  • 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.

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • TarynRMT Taryn Diven (@TarynRMT) reported

    @O2 @rosalyn129 Careful, Rosalyn. My husband hasn't had any service from O2 for 6 weeks now because of a mast issue, and they won't let him cancel his contract without paying a cancellation fee of £519.

  • EOscroft emma oscroft (@EOscroft) reported

    @O2 absolutely diabolical customer service team

  • kainebarr Kaine Barr nffc (@kainebarr) reported

  • farali84 Farrah Ali (@farali84) reported

    @O2 got a new Vodafone contract today, will be switching from o2. Worse service ever. Bad service in my house for years and nothing been done. 2nd contract I've had to switch. Glad to see the back of o2.

  • councillorjoe Cllr Joe Whibley (@councillorjoe) reported

    @O2 hi, I'm trying to move my number to a new o2 payg contract which started a week or so ago. I have PAC code. Online does nothing, not even email acknowledgement, and phoning never let's me speak to anyone and cuts me off. Incredibly frustrated and not happy. Any ideas?

  • Dave_G_Grant David Grant 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@Dave_G_Grant) reported

    How does one get an #O2SurpriseBox from @O2 Does being a customer for 20yrs qualify? I doubt it 😢

  • ColfinCaptures Kathleen M (@ColfinCaptures) reported

    @O2 It just tells me the network is busy

  • ejw1601 Emily W (@ejw1601) reported

    Looking at a THIRD week of no mobile signal from @O2 . Brilliant.

  • evisugenius Damn Daniel (@evisugenius) reported

    @O2 having wifi issues since this afternoon, care to explain?

  • CathyEllis121 Cathy Ellis (@CathyEllis121) reported

    @O2 Can someone please sort out getting an esim set up?? Live chat not managed to help and online needs to text me a code - which I can’t receive as not on network on new phone. Really frustrating and thinking of giving up and switching provider.
