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

    5th day in a row I've had no signal or data through to my phone. @O2 is going downhill. Definately on its way out. This is so poor I shouldav stayed with T Mobile. #O2 #POORCUSTOMERSERVICE

  • RobertBlevin Robert Blevin (@RobertBlevin) reported from Guildford, England

    Hey @O2 - I’ve had appalling voice and data reception for months. I spoke to your shop in Guildford 2 weeks ago, and they said that it was a known issue + signed me up for text alerts. Now you text me every few days to say you haven’t fixed it. 1/2 ...

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • 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

    Is anyone else experiencing call drop outs and freezes on #iPhone11ProMax I have cleared cache and done soft reset, also had a sim swap @O2 but still having buggy experiencing overheating. I’ve checked online and have reset my network settings. Minded to pop into @Apple

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

    @O2 has GENUINELY the worst Phone line #Customerservice system ever. I've never been more infuriated just waiting to give a password or speak to someone. Please #O2 update your system to 2019 standard asap.

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • BecOz14 Bec Osborne (@BecOz14) reported from Camberley, England

    Have had 1 bar of @O2 signal for most of this year, funnily enough when I tested the signal strength back in July the signal jumped to a MEGA 2 bars momentarily. #NoServiceHere

  • ANDREW0675 Andrew Leason (@ANDREW0675) reported from Woodley, England

    @O2 Yeah about those LOL up to end of last year I had no issues at all getting the weekly free hot drink at Cafe Nero while this year I think I have been able to get it only once or twice as always been out of stock both days 😫😂

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

  • HannahHoldswor2 Hannah Holdsworth (@HannahHoldswor2) reported

    @O2 It’s been a very rude Irish man the last few times from 08009524854 . I’ve tried blocking the number but it’s still coming through

  • ryanstoptryan ry x (@ryanstoptryan) reported

    @O2 any chance of a reply please? Not had any service all day since transferring my number over from voxi...

  • SiobhanGunson Siobhan Gunson (@SiobhanGunson) reported

    @O2 I assumed on my bill the amount was part of my monthly phone bill, feel so upset and stupid for not noticing that I was being charged for texts for so long, but it was very sneaky! I get so many scam texts and phone calls I blocked it thinking it was a scam too.

  • Markus_Astbury Markus Kane (@Markus_Astbury) reported

    @O2 you’re a company that lies to its customers, I had explained my current predicament, was on a payment plan, yet you still disconnect me. That isn’t even the worse part, trying to call an actual human from your side is borderline impossible. New network for me 🖕🖕🖕

  • nicuteo Nicu (@nicuteo) reported

    @O2 I am biting my hands off for ever thinking of joining your network. Have been on the phone/chat with your reps for a week now, trying to sort out a botched number porting, but nobody seems to know what to do. Maybe telecom is not your thing after all?

  • ElleB101 Elle 101 (@ElleB101) reported

    @O2 Morning. Reported. Knew it was scam hence contacting you & no intention of following the link! Thanks for the help.

  • lou_emii Ema (@lou_emii) reported

    @O2 I am getting beyond annoyed with the company. twice I have spoken to CS regarding an insurance claim both times told I'd receive an email which I have not! I am abroad needing my phone replaced immediately - I pay for the service yet you seem to just be taking my money

  • FelixLayi Felix 'Layi (@FelixLayi) reported
