  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from London Colney, England

    Is there a hashtag for awful customer service from @O2 and/or @DHLParcelUK ? Asking for a friend.

  • peterives50 Peter Ives (@peterives50) reported from Enfield Lock, England

    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • shazzstevo Sharon Stephenson (@shazzstevo) reported from Enfield Lock, England

    @O2 My calls keeps dropping. This has been happening for several days now. This is really poor service. This is in the Enfield area

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

  • gadgetgem Gem (@gadgetgem) reported from Barnet, England

    Missed out on my free sandwich this week @GreggsOfficial with @o2 due to the scanner being broken again. Went to next nearest greggs and they had no breakfast 😢 #o2priority #greggs #breakfast

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • ksjsowhat fiono (@ksjsowhat) reported from Barnet, England

    @O2 I made an order on the 27th of October and it’s still not in process, I absolutely need the phone I ordered within two weeks, could you help me please ?

  • VictoriamariaC Victoria Clarke (@VictoriamariaC) reported from Walthamstow, England

    @O2 please can I ask why you have left a 76 women who has just lost her husband and undergoing cancer treatment without any phone service and no one is able to help. Absolute disgrace @lec1479

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

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

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • cove123 mark nicolson (@cove123) reported from Welwyn Garden City, England

    @O2 opened app to use bacon sandwich offer local greggs not open yet for some reason @GreggsOfficial Wgc poor

    Really getting pissed off with @O2 never seems to want to use it’s own data even when I have 4G

  • sunkfarmer Jono Dixon©️ (@sunkfarmer) reported

    UPDATE RE MOBILE SIGNAL ISSUES.. This is from @CMC_LTD #Ashleigh Guess what and of no surprise @o2 have done all they can do to fix the problem and are unable to be of further help. They've closed the case. THIS HAS GOT MY HECKLES INTO GEAR. @BBCWatchdog please contact me

  • chez197734 cheryl hind (@chez197734) reported

    So @O2 is so rubbish with data can’t get more than 3G anywhere and it’s so slow time to change

  • RamblingSailor Mark (@RamblingSailor) reported

    @O2 could I have details on how to complain please? I raised various signal issues in North East #Leeds and nothing has change since 16th August, and not even received a “We’re still working to fix your issue” text recently.

  • GAWE14 Gary Wilson (@GAWE14) reported

    @O2 not impressed by the very poor customer service when trying to upgrade to new iPhone. Been with O2 for many years not happy

  • ReissOmari Gordé 🕊 (@ReissOmari) reported

    One day I’ll be able to listen to @AppleMusic without seeing “Request Timed Out” loool @o2 if I get a 5G sim and my signal STILL doesn’t work can I return??

  • AngharadParry3 Angharad Parry (@AngharadParry3) reported

    @O2 paid a visit to your Preston store today for an E sim. They had issues setting up, now i know why. My fiance had a go when we got home. They have only given me an E sim pack. Registered to someone else thats still active. On a different number to mine GRPR? What GDPR?!

  • Giulio_ferragut Giulio F. (@Giulio_ferragut) reported

    @O2 the network in Southwark (London) has been awful for days. Any chance of this getting sorted before the end of the year?

  • dannog_8 Dan (@dannog_8) reported

    @O2 remind me again WHY I’m this company £50 a month for a service that is quite frankly appalling? I have 20GB download a month and it’s barely used up due to the appalling loading speeds.

  • ButtersHewitt Mark Hewitt (@ButtersHewitt) reported

    @o2 Still no data services in Cranleigh (GU6). Shows full signal on 4G but that’s not representative of the current service.
