  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • tobyd360 Toby (@tobyd360) reported from Farnborough, England

    @O2 I’m stuck! Trying to upgrade online, on the last screen realised it was the wrong GB model of iPhone 11 - seemingly can’t cancel it from there myself? And if I go back and click to upgrade again, it just brings up the load screen forever 🙁

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    If your an @O2 customer be careful I’ve had emails and texts saying I owe my bill and I checked through my App and I don’t owe anything. #FraudAwareness

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    So now I’m without a phone and will never know where or what happened to my iPhone all because of poor customer service from Hassan in the @O2 Lewisham Branch! So much for customer service! #disgustedcustomer @BBCWatchdog

  • HaleAlexander Alex Hale (@HaleAlexander) reported from London, England

  • sally290718 sally (@sally290718) reported from Farnborough, England

    @marcwhufc @O2 That's shocking as it was next day delivery, @02 customer service at it's best........NOT

  • Avigazed Avigazed (@Avigazed) reported from Addlestone, England

    @O2 How long does it take to port a number from another network to o2? Surely 2 days is a bit long.

  • oliviakhwaja Olivia Khwaja (@oliviakhwaja) reported from Sunningdale, England

    @O2 great marketing activity. But no good doing that if you can’t provide basic service. Have been trying for 2 weeks to buy a new SIM. Passed around everywhere, 40 minute waits, given phone numbers by your South African call centre that don’t work. Not feeling like centre stage.

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 I need a customer call back please.

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • AmiStreets Ami Streets (@AmiStreets) reported

    @suziestreety @O2 They’re awful! I constantly have zero signal and barely receive any calls through to my phone yet when I’ve complained about it and wrote to them they “can’t find any faults in their service” and wouldn’t do anything about it. Think we should move to another network!

  • ColourAnxiety9 SałtŷŠeñpaï (@ColourAnxiety9) reported

    @O2 why in ******** has my Samsung Galaxy just come with a charger cable with no socket to actually CHARGE my phone? Literally £1200 phone with no charge socket and no earphones.... regret swapping already. ******* joke

  • philipeo121 Phil Carter (@philipeo121) reported

    Well @O2 you do it again customer service is appalling!! Been on the phone 30 min and been disconnected 3 times!!! Your phone line is terrible and you can’t help me with a faulty handset ! Trouble shooting of turning phone on and off is pathetic!

  • SarahTonin_88 Sarah (@SarahTonin_88) reported

    @O2 @suziestreety I really hope your solution isn’t going to be an ‘upgrade’ which she has to pay for?

  • KatieBart87 Katie Bartlett (@KatieBart87) reported

    @O2 Like I already said I don't have access to another device or I would of done that already. So if I call today noone will help me if I can't receive a code?

  • derek_mallett Derek Mallett (@derek_mallett) reported

    @O2 received a SIM card which I didn’t order, customer service told me to bin it. Why was it sent to me ?

  • KatieBart87 Katie Bartlett (@KatieBart87) reported

    @O2 good evening! I'm trying to upgrade my phone and before I can check out it is texting a verification code to confirm. My old phone is broken so I can't access the code. Can you please help?

  • Jennife14435458 JenMet75 💙 (@Jennife14435458) reported

    @O2 why is the signal so bad where I live, you claim good indoor and outdoor on 4G, Im lucky if I have 1 bar!!!!

  • DMcstravock danny mcstravock 💙 (@DMcstravock) reported

    @ninasbib @O2 What a load of bullshit biggest load of scammers I ever came across from a soon to be ex @O2 customer treated with absolute contempt

  • pickled_tinker Ian Grody (@pickled_tinker) reported

    "Get EE or get network envy" is, if anything, misinformation at it's greatest. I use @VodafoneUK and @O2 and in no way envy your network, your users and especially your overpriced and under valued deals. Can get the phones I want with better deals and cheaper here.
