  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

    @O2 I have also been doing this too. If this problem persists, then what?

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

Latest outage, problems and issue reports in social media:

  • jenvalentine86 Jenscrine (@jenvalentine86) reported

    @Oilyduck65 @O2 I’ve barely ever got signal although their network checkers said I did when I joined, only 2 months into new contract.

  • AyadGazi Ayad A Al Gazi (@AyadGazi) reported

    @O2 O2 most definitely is one of the worst networks if not the worst ever!!! Over 6 weeks of complaints and over 537 minutes of telephone calls and over 10 promises of call back…yet nothing has happened!!!

  • b_nockbhoy83 SuperFurryBrazza (@b_nockbhoy83) reported

    @O2 how come despite being an O2 customer for many years my upgrade deal is nowhere near as good as if I’m a new customer for the exact same package? #riddlemethis

  • Chloe_Louise92 Chloe Lousie Selby (@Chloe_Louise92) reported

    Absolutely shocking service from @O2 the past few days, including being hung up on and not being able to get through to being told to source materials on ebay and give them a call. After 10+ years being a pay monthly customer, I'll be leaving at the end of my contract. #appalling

  • lucyolivia19 Lucy (@lucyolivia19) reported

    @O2 Nowhere, I’ve been travelling quite a bit recently and it doesn’t load even when I have full signal. My partner is on o2 who is next to me and can always get data and I can’t.

  • thisisjmx J∆MES 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported

    @O2 I've lost count on how many times I've unsubscribed from network updates over SMS & I still get them. The number hasn't been on your networks since 2019. CF644QS. If I DM U, Can U please make sure it is removed?

  • NW_SAR LASAR_Gary (@NW_SAR) reported

    @O2 Been to my local @Tesco store and their system wouldn't let me have a top up voucher. I also don't have a e top up card. Phoning in via 202 or 4444 doesn't work either.

  • tomgstott Tom Stott (@tomgstott) reported

    Completely unable to use any data at all today despite 4 bars of 4g. Utterly sick of it now @O2 it really has been months and all O2 users I know here having the same issues. Had enough. Just going to consumer affairs programs and local media to see how many others affected.

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 your customer service is the worst. Your customer service advisors wouldn’t cancel my contract. They said I have to talk to retentions but I don’t want to speak to retentions I just want to end my contract. 😭😭😭😭

  • apakula Andy Pakula (@apakula) reported

    @O2 simply say that they are within the law to keep my £5000+ even though I've never used it. Watch out for direct debit abuse and watch out for @O2 in particular!
