  • daishughes daisy (@daishughes) reported from Kingston upon Thames, England

    @O2 saying that they will be posting my new phone to me because my local store is closed but haven’t sent me a single email or even a tracking number? Trying to speak to someone but all 202 do is hang up on you and nobody replies to dm’s😕

  • 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

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before - I’ve now tested on both front and rear cameras with and without HDR and it bleaches every time. Is the product faulty @AppleSupport or is this an iPhone 12 issue in general. How can I fix it?

  • 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

  • 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?

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

  • 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

  • Si11y3gg Pawlie (@Si11y3gg) reported from Richmond, England

    @VixSeaman @EE @O2 I’m with o2 also! Was with Three before, but would never bother with EE. I will only do sim only.

  • 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..!

  • 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.

  • 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 🥳🥳🥳

  • 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.

  • nickshuttle Nick Shuttleworth (@nickshuttle) reported from Ealing, England

    @O2 can you explain why I cannot transfer my eSIM card electronically? Surely that is the whole point of eSIMs? I now have to wait 5 days to receive a new pack before I can transfer my phone. Seems archaic. Unimpressive customer service.

  • 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.

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 I’ve tried desperately trying to get hold of customer service and keep getting knocked off. I need a 5 g SIM card for my new iPhone 12 pro plus and need a 5 g sim , I think a card may be ordered but not the 5 g

  • 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!!!

  • 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

  • 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?

  • hedaramusic hedara (@hedaramusic) reported from Hammersmith, England

    @O2 absolute JOKE of a service today. Got a deal offered to me by your retentions team TODAY, I ring back later to call it and no one with authorise it. Been passed to and fro for an hour and a half and got NOWHERE. The phone and deal I want is sat in my basket. Help.

  • sarahbb1 Sarah BB (@sarahbb1) reported

    @EstjamesC @O2 Sadly not my experience. Just want them never to cut me off when I travel but clearly asking the impossible - despite paying hundreds a month...

  • Gwam007 Gwamzy (@Gwam007) reported

    @O2 customer service. Very poor response

  • _neyneyy NO.1 (@_neyneyy) reported

    @O2 My mobile network. No signal no nothing when I’m outside but as soon as I’m in my house. Viola.

  • adam_peat adam peat (@adam_peat) reported

    @O2 big shoutout to o2 for ripping down the mast near my home, not telling anyone, leaving people to suffer while they "talk to local authorities" and still expect people to pay full price for a service they are not currently providing

  • Tytthaspis16 (((bugs))) xo (@Tytthaspis16) reported

    @Rachyfarrimond @O2 I had the same Issue today trying to get sent a replacement sim card and got absolutely nowhere after 1.5 hours

  • PCgonemad1066 me (@PCgonemad1066) reported

    @O2 Well I pay my bills on time and I upgraded in November. I spoke to customer services now and they don’t why they’re calling me either. The automated service annoyed me. Grrr see that’s why I don’t talk to you and do it once a year. The less I call means you have great service!

  • StevieMcB77 Stevie McBeth (@StevieMcB77) reported

    @O2 nice of you to cut my phone service and not calling to simply ask to update our CC. A text would have been nice to warn us! Now from 5 handsets we are down to only having 2 with you and I will be entering a complaint as you left a vulnerable person with no means of contact!

  • TarynRMT Taryn Diven (@TarynRMT) reported

    @O2 @Clamfather Start by fixing your masts. That's 7 weeks without a signal now. Credit to @EE for providing me with an excellent signal that my husband uses to call O2 to hear their lies, false promises, and catch phrases such as, "We can't guarantee a fault free service."

  • DavidSm12327782 David Smith (@DavidSm12327782) reported

    @O2 @OakNational I would advise against any sort of business with O2, they have just the worst customer service ever. They refuse to engage with customers on the phone or by email, any issues they just don't care about and pass you from pillar to post but nobody will own a problem to completion.

  • MarinaMacTavish Marina MacTavish (@MarinaMacTavish) reported

    @O2 hi I'm having issues with my data when outside. I can only connect to the internet via WiFi
