    @O2 hi, this morning I ordered a case from your website and it said there was a problem, but my card provider is saying the payment has gone through. Can you confirm whether this was the case or not? Thanks

    @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

  • 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?

  • 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.

  • 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

  • saps_JP John (@saps_JP) reported from Stratford, England

    Seriously @O2 literally just taken out a contract with them and already worst service!!! Phone hasn’t arrived and was supposed to last Friday, only to find out it was sent back. Now I have to wait til they receive it and reorder another one.

  • MCFCLondon Tueartsboots 🐝🌹✝️🇬🇧🇺🇸 (@MCFCLondon) reported from East Ham, England

    @O2 how come i can get a phone signal under the Thames on the Jubilee line but zero signal on Shooters Hill, SE18?

  • 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.

  • AledSmith Aled Smith (@AledSmith) reported from Camden Town, England

    @O2 why is it so hard to get your systems to work properly. Don’t give me automated messages telling me I am overdue with my bill when I am not. Then sort out your customer support. How can your AI engine be too busy to ‘talk’ to customers. Rubbish.

  • 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?

  • J5752x Jay S. (@J5752x) reported from Paddington, England

    Went to @O2 #TCR to swap my monthly contract onto a prepaid card. I was told it has to be done over the phone and they can’t issue a new SIM in store. Went to @EE and asked if I could transfer my number to them. The seem enthusiastic

  • yasirkiani22 Yasir kiani (@yasirkiani22) reported from East Ham, England

    @O2 it’s been three weeks now and very poor customer service no response???

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

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

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Tottenham, England

    @O2 You have had this problem for the last 20 years doubt a self help guide will work. Ive made several complaints so end of contract I will be looking for a new service provider ...

  • Maria__RG María (@Maria__RG) reported from East Ham, England

    @chellemccann @FitBits_ @O2 I have been trying to top up my phone for the las 3 hrs with no success - i believe their system is down, quite annoying!

  • 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?

  • 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?

  • KJWXXX KJW (@KJWXXX) reported

    @o2 No signal or service now for 2 weeks- missing vital calls and texts about an elderly relative-

  • No1Deathy J (@No1Deathy) reported

    @Beathhigh @O2 I thought it was just me with my internet signal, very few and far between, and I'm down London way!

  • hamilton45_j Jane hamilton. 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 (@hamilton45_j) reported

    @Beathhigh @O2 Getting signal but weaker than usual - EH112JU

  • YvetteM94 Yvette Marie (@YvetteM94) reported

    Anyone else with @o2 having problems in the ME19 area? Not been able to use my phone at home for the last 4 days! Starting to become a joke now 🤬🤬

  • Kittyfarrell Kitty Farrell (@Kittyfarrell) reported

    @O2 appalling service this month. Days without any form of signal then text messages stating “you’re waiting for the landlord” to be able to get in and fix the mast. Absolute joke. Yet I’m still expected to pay the bills that you’ve increased in price..

  • lisapkennedy Lisa Kennedy (@lisapkennedy) reported

    @O2 The horrific customer service you offer. I've reported them to offcom. Offcom is unable to get involved in individual cases. If enough people complain, they will investigate

  • Beathhigh Ian Rankin (@Beathhigh) reported

    Any @O2 customers in Edinburgh failing to get a signal on their phone? I’m currently reliant on broadband.

  • 1JackWebster Jack Webster (@1JackWebster) reported

    @O2 can I ask why the service on my phone simply doesn’t work when automatically connected to 5G? With an increase of 5G masts being installed, the future with O2 doesn’t look promising if it continues in this way?!
