  • 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!

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • 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

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

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • bks67 bridget sparks (@bks67) reported from Hertfordshire, England

    @O2 I do have the app, I think I will phone the customer service team and ask them,

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

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

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

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • 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

  • 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.
