  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

    @O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

  • benjaminlfc Benjamin Webster (@benjaminlfc) reported

    @jcrrn_ @O2 I got the same and I managed to get to the end of the checkout essentially. Had to call, they had to cancel the order and put it back through

  • peepvato - (@peepvato) reported

    @O2 my phone won’t let me get past o2 switch up - it’s agreed to the switch up I get to the final check out page and there is an issue with my “switch up selection” by there isn’t.. and I have never used my switch up until today…

  • DannyHo00396186 Beastlysimmer_uk (@DannyHo00396186) reported

    @kornsteven @O2 O2 seem to not respond on x anymore, i can help you out throug as i recently upgraded on switchup with a pre order

  • francestom francestom (@francestom) reported

    @o2 ‘sigh’ I have been trying to use the app, but each time I enter my email and click Forgot my Password, no link comes to my email. Your bill did. Can u fix it.

  • benjaminlfc Benjamin Webster (@benjaminlfc) reported

    For anyone having an issue when ordering the new iPhone from @O2 when trying to use switch up and the upfront cost is showing as what you fully owe for the phone you need to get to the basket page before it actually updates to just the £1 upfront cost, obviously getting to the basket page is proving difficult but it does update to £1 once there

  • callumjohn28 Callum (@callumjohn28) reported

    I have to say… @O2 the WORST when it comes to upgrading. You have to have a better system in place. As it’s the same issue every single year. 🤯

  • Eimears_Wish Eimear’s Wish Creating Hope (@Eimears_Wish) reported

    @O2 hi why is your 2220 number not working today

  • DannyHo00396186 Beastlysimmer_uk (@DannyHo00396186) reported

    @kornsteven @O2 Then when they receive your old device they will inspect it and if its in good enough condition they will terminate your old contract, bare in mind both your old one and new contract will be active and if you dont send your old device in quick enough you will be charged for both

  • camthetank123 Cameron Ellis (@camthetank123) reported

    @O2 2/3 I have been a customer or 18 years and in total spent over £24,000… the debt can be resolved in 2/3 weeks and they have said … I have no phone and when wanting to speak manager they say can call back but been disconnected so call just ends …

  • DannyThat7 Danny (@DannyThat7) reported

    @O2 afternoon any reason why it been over a day and no signal in the halesworth, Suffolk area?
