  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • ninavdbennett Nina Van Driel (@ninavdbennett) reported from Windsor, England

    @O2 I am sorry but I am simply shocked at your poor customer service. I have now called twice to complain and ask for help. Twice I have been told a manager would call me. Twice this has not happened.

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUK been a loyal customer for 6 years, recently brought a new contract through you, yet my upgrade price is far from being a loyal customer, I cant even get an existing customer deal unless I take out a third contract, what a joke! Even @O2 are cheaper than what I was told

  • 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!

  • 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.

  • owengmusic Eoghan (@owengmusic) reported from Bracknell, England

    @o2 Ive transferred over to another network but I cant use my phone because you wont unlock it after 2 store visits (Wandsworth and Bracknell) very frustrating

  • SaintGeorgie Georgie Tongue (@SaintGeorgie) reported from Wokingham, England

    @O2 I spent hours on chat to your advisers trying to cancel my phone contract and was told it was all done. I started a new contract with another provider and now suddenly I have been started on a new o2 tariff??? Help!

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. Help!

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

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

  • Ricardo_7united 🔻ᏒᎥፈᏂᏗᏒᎴ ᏕᏗᏁᎴᏋᏒᏕ/Ⓡⓔⓓ ⚽️🥅🎮🍪🍻 🔻 (@Ricardo_7united) reported from High Wycombe, England

    @sophdefoe92 I had that problem on @O2 but managed to sort it out

  • 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..!

  • 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?

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

  • 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

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • bethanyxhewitt Bethany Hewitt (@bethanyxhewitt) reported from Bracknell, England

    Experienced some of the worst customer service to date!! First the advisor takes £400 more than agreed, next I’m chasing advisors everyday for a month with false lies about refund dates @o2 #notacceptable

  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need me.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    Hello @O2 I am back 🙌🏻 after a few years with no signal, awful service I have come back with my tail between my legs 🙈 #ohtohavesignal 🥳🥳🥳

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUKSupport I want the note 20 4g but was told for 30gb £58 a month with a upfront cost, where as my "customer exclusive offer" was £55 a month. Or I can can to @O2 and get 90gb for £51 a month with a less up front cost. Talk about customer loyalty!!!

  • Crofty7777 Dan Croft (@Crofty7777) reported

    @jodielouiseart @O2 Mine is exactly the same it’s a joke of a service I’m certainly changing networks when my contract is up

  • Learosexx Lea (@Learosexx) reported

    @o2 increasing our bills so they can ‘ power their network’ maybe use some of the millions of profit you made last year yeah?

  • Inquis_chap Laurie (@Inquis_chap) reported

    Phoned virgin mobile to upgrade my, and my kids, contracts & they said they'd merged with @O2 and new contract had to be with O2. Only 2 of 3 numbers set up. Now nearly 2 hrs into being bounced around depts and still not sorted. The worst customer experience I've ever had

  • murray_sfcm1969 shaz.☘️YNWA (@murray_sfcm1969) reported

    @o2 As an @o2 customer I’m disgusted at the recent news of price rises from April. I will actively be looking for a new provider.

  • aleighsonc ✨𝔸𝕝𝕚 ✨ (@aleighsonc) reported

    @O2 why has your service got worse?! You used to be one of the best but lately you’ve been shocking. The odd occasion when I have to toggle between you and my so-called ‘fibre broadband’ is absolutely painful

  • navnabi Nav Nabi (@navnabi) reported

    @O2 I have to say I’m very disappointed in your price increase. Never seen an increase like it. I was thinking about changing my Virgin Broadband to Community Fibre, looks like my O2 contract will be switching to someone else now too. Bad move, your really don’t need to do this!

  • KelayJames89 James Kelay (@KelayJames89) reported

    @TheTacticalBrit @O2 Unfortunately for us lot stuck here in the uk @TheTacticalBrit Tesco is our only choice of mobile network now as they won’t put up there prices 👍

  • garfster2609 Gareth Cornelius (@garfster2609) reported

    @rinsure @EnglandRugby @O2 To be fair Ben has been out of the squad since Sunday night. So missed 1 day. If he had never been in I’d be more surprised

  • celticghirl_bee Bee 🍀💚 !! (@celticghirl_bee) reported from Crieff, Scotland

    @O2 what's the point in having customer services. If I wait for ages to get through to correct people. Only to be hung up on numerous times and then try online chat and get told too busy. Try again later. Absolute shambles. Will never recommend o2 to anyone I know. Shocking

  • t_hambrett Tom Hambrett (@t_hambrett) reported

    @virginmedia failed to disclose to new customers that their @O2 5G SIM for £12/mth was an optional add on - have now been cutoff 4x times by the O2 customer support team (as an existing customer) when trying to cancel subscription. Anyone else had this before?
