  • 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

  • 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

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

  • 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!

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

  • 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.

  • 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

  • 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,

  • 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

  • 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!

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

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

  • 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.

    @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. #

  • 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

  • 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

  • sessions_jo Jo Sessions (@sessions_jo) reported

  • Silvia26p Silvia (@Silvia26p) reported

    How do you get a new contract with @O2 ??? 35mins on the phone pressing 1 for sales over and over. Yesterday same 25mins and gave up. Awful service!! @O2 Don't you want new customers???

  • Pat__Turner Pat Turner 🎗️ (@Pat__Turner) reported

    @O2 your customer processes and services are appalling. Every time i fill in the form to port my old number it errors out. Your live chat is permanently busy. Call waiting over an hour. Earliest call back option is 28th Jan. What a joke

  • buntyshah007 Bunty Shah (@buntyshah007) reported

    @O2 saying the code is invalid - help!

  • trigmk2 Alex (@trigmk2) reported

    @O2 I've been on the phone for 1.5hrs, bounced around depts trying to return a faulty S21 handset within 30 days to be told you no longer stock it. I can have a previously returned handset, or cancel my contract & take out a new, more expensive contract, on an inferior handset.

  • EllyEllygoodman Elly Goodman (@EllyEllygoodman) reported

    @O2 o2 you are the worst provider I’ve ever come across we have been treated appallingly and no one seems to care or provide us with a solution - im beyond furious

  • Fraggle05 Fraggle (@Fraggle05) reported

    @O2 I would like your CEOs contact details as frankly your customer service is appalling. 5 weeks I have been attempting to sort an issue with your company and it has now resulted in you taking £200 out of my bank account incorrectly and refusing to refund it for over 3 weeks.

  • Sri2Sree2 S r e e (@Sri2Sree2) reported

    @O2 But how is that going to help??? Do you guys even act on them n catch them and take necessary actions??

  • craigypickle craig (@craigypickle) reported

    @O2 hi, if I was to take out an o2 sim only contract via uswitch, can I transfer my current number from my previous network?
