    @lollylaura40 @samantha00861 @O2 Hi, I have same problem sky seem to have the best deal, I really don’t want to leave o2 but I can’t justify paying over £56 a month when sky will do the same for £49 and you can get money back with topcashback

  • 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

    Mother has been getting scammed by a mobile app service "Lasevia limited" for past 8 ish months, her mobile provider @O2 can't help at all. Looking online this has been an issue for ages yet nothing has been done by O2 😡

    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

  • 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.

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

    @cleggytaxi @O2 Yep you’re right. Signal dropped again.

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

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

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • 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

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • Stephen72798722 Stephen Robson (@Stephen72798722) reported

    @O2 I’ve never experienced such shocking customer service. Breaking 3 promises in a week must be a record, along with staff saying their colleagues will get sacked for their conduct ?! No place for such behaviour in todays marketplace. #badservice#skydoitbetter

  • iancackett Ian Cackett (@iancackett) reported

    @O2 after several hours failing to get a one-time code from you (told your systems were having problems), I've now hit some kind of limit (told it can't send more codes... despite me receiving none). Assuming this limit resets tonight? Or do I have to wait a full 24 hrs?

  • Beeestonia Lord Beestonia🐝 (@Beeestonia) reported

    Looking to buy a new phone as current one knackered. Seems the @O2 shop has now closed in Beeston. Ah, best online anyway. Log into O2 app, that promises to send me a confirmation code to log in. Code never arrives. Gave up. What's a good way to get a phone these days?

  • DjFriskyD DJ Frisky D ️ (@DjFriskyD) reported

    @O2 my voucher was used but I was told I need to pay by the assistant at the Bury Street, Edmonton, branch! Not really a happy customer ! #Greggs

  • nw_peaches Peaches (@nw_peaches) reported

    @O2 Same issue happened with two different phones both with old sim card and with new sim card. I doubt highly that two phones are faulty when with another service providers sim both work perfectly. I’ve had terrible service with o2 for the duration of my contract and it’s worse now

  • NaylorLFC Simon Naylor (@NaylorLFC) reported

    Worst thing I ever did was switch from @VodafoneUK to @O2 Pathetic service and customer service is just as bad

  • finkcreative Alex Lieven - Design & Art Director (@finkcreative) reported

    @o2 is now to 3G. Wtf is going on?

  • emilyplaysacnh emily (@emilyplaysacnh) reported

    @O2 Having the same issue again this month as the previous. The direct debit you set up didn’t work and I’m not getting anything from anybody on the 202 line. Please help, you’ve threatened to cut off my device today and not reconnect it!

  • titchyboy41 Titch (@titchyboy41) reported

    @O2 Why is your mobile phone signal so bad in ML3 ? At times the best you can manage is 3G.

  • iancackett Ian Cackett (@iancackett) reported

    @Fiendish1k2 @O2 Me too. Reported and acknowledged as an issue at their end. Will try later this evening.
