    @O2 customer services truly are as much use as an ashtray on a motorbike.

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

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

  • 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.

  • 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...

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • 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!

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

    Poor network in Se6 @O2

  • 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

  • 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.

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • monicathenurse Monica, BSN, RN, MFCI (@monicathenurse) reported from Walthamstow, England

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

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

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • 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

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • 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.

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

    @O2 Fixed the issue. Turned Volte off, rebooted, turned back on and got wifi calling back :)

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

  • thekinaton Jason Sensation (@thekinaton) reported from Brighton and Hove, England

    Seems @O2 priority @ODEONCinemas tickets have all expired the day of issue.

  • CorbettAndy andrew corbett (@CorbettAndy) reported

    @O2 a week ago I reported that we have no signal in the area. So far you’ve established I didn’t know I had a password for my account. Please fix the damn transmitter mast.

  • jadealmann Jade Mann (@jadealmann) reported

    @O2 All credit checks are completed by the network rather than ourselves. They consider a number of different factors and take these all into account when running the credit check. Unfortunately, we are therefore unable to provide any specific reasons. Their reply?

  • rachaelburt1 Rachael (@rachaelburt1) reported

    What is it with @O2 and signal levels lately. Past few weeks they’ve been appalling and my 4G barely working properly. According to their website though, nothing is wrong 🙃🙃

  • annataft_ Anna (@annataft_) reported

    @hollypepper__tw @Clo_TheWantedx @O2 Really 😳😳😳😳 I can’t believe I’ve only just noticed wtf. X

  • kennypowders76 ⚽️ⓢⓒⓞⓣⓣⓨ⚽️ (@kennypowders76) reported

    @npjy83 @virginmedia @O2 Yep, twice now trying to sort an issue, over half an hour each time and no one available apparently. 🤨🤨

  • npjy83 Nathan Young (@npjy83) reported

    @virginmedia Worst customer service on the planet. Tried to get Vault set up between Virgin Media and @O2 and the the VM advisor was trying to get me to purchase a new SIM card for £12 a month.

  • LMSBOSSY Angela Dobb 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@LMSBOSSY) reported

    @O2 hi O2. We have no service in AB51. Again. Please advise on when service will be resumed.

  • _LucyDxx Lucy♥️♥️ (@_LucyDxx) reported

    @O2 what is going on with your service just now? When will it be fixed? I’m in Glasgow, but seems to be a UK wide issue

  • Adi770839136 Adi7 (@Adi770839136) reported

    @dean_mackintosh @O2 You're right when you say there's no point. I too was a victim of fraud thanks to O2 (to the tune of £700). As if that wasn't bad enough in itself, they choose to side with criminals over customers and tell me there has been no wrongdoing.
