    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • 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!

  • 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.

  • 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

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

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

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • 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

  • 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?

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • Cliodhna1996 Cliodhna McGivern (@Cliodhna1996) reported

    @O2 Clearly all your customers have problems if it’s taking this long for response and adequate actions! I just want my refund which I’m entitled to nothing more nothing less and for the lies and false promises to stop!

  • jamesfrhodes James Rhodes (@jamesfrhodes) reported

    @O2 need some help - new iPhone in February, previous info/data transferred from old iPhone. Green text messages not sending to anyone without iPhone (message send failure every time). Need this fixing ASAP but can't get hold of an O2 advisor.

  • _murraybowman Murray Bowman (@_murraybowman) reported

    @o2 so you’ve turned my service off again after saying you fixed an issue on my account. I’m now back to being left without any service!! Worst decision joining @o2 😩😩😩 being told the classic, it’ll be 5 days before we can look into it, rubbish!!!

  • BillLdn billy c (@BillLdn) reported

    @O2 its not building material inside and out i am having issues, i can place my phone to the window where there is minimal material and still have issues dont pull that one, my partner on EE has full coverage so it cant be building material, unless the o2 signal is inferior to EE

  • ErikDoIt Erik de Wit (@ErikDoIt) reported

    @O2 no signal. On phone with your colleagues via different number. Great to see you get people in SA to work for problems in the UK. However it be great that they call back on the number as promised. Rather than me wasting 31 mins get hung up to do a test and no call for 2 hrs

  • anotkatod Anot Katod (@anotkatod) reported

    @O2 worst customer service I've ever seen in my life thank you o2 you should be ashamed of yourself there is a service you can't provide

  • johnpudneyhq John Pudney (@johnpudneyhq) reported

    @O2 I appreciate that, and I really do understand that this isn't your fault. But it remains an absolute p***take to charge me for a service you know you can't provide and to want to charge me more than is left on my contract to leave early. That's abysmal customer service.

  • anotkatod Anot Katod (@anotkatod) reported

    @O2 In 2022, non-working e-sim broken gsm network bravo👍

  • nat_mortimer 🖤 (@nat_mortimer) reported

    When @thisisheart ring you about #heartmakemeamillionaire but your @O2 signal is so **** your phone doesn’t even ring - just gives you a text notification! I am devastated 🥲🥲🥲🥲🥲 #cursed #notgoodenougho2

  • Cliodhna1996 Cliodhna McGivern (@Cliodhna1996) reported

    @o2 need to provide stores for people to go into instead of their call centres since you can’t fob people of to their faces! Not going enough that local stores are only worried about sales as opposed to customer service
