  • 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!

  • 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

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • 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. #

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

    @TazPDN @O2 So sorry to hear that ,#o2 is really bad, I'm with Vodaphone and they are much much better . Hope all get sorted for you x

  • 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

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

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

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

    @O2 what is going on! 😭😭 Even when I have signal it's so slow!

  • 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

  • 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,

  • 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!

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

    @O2 How did this shit happen

  • 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

  • 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.

  • 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

  • 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.

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

    @BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

  • 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!

  • Richard97324518 Richard Hardy (@Richard97324518) reported

    @O2 Shocking service from this company! Sold a contract with No Phone. Blaming 3rd parties for the mistake but happy to run hard searches on your credit report, Bill you and take money from you! When people are at home vulnerable and need their phones to communicate.

  • weyland76 Matt (@weyland76) reported

    Gotta say @O2 - your upgrade "deals" are so ridiculously expensive, there is literally zero reason for me to stay as a customer instead of just going to another network for a much better and cheaper outcome. 👎

  • teachquietly Secret Teacher (@teachquietly) reported

    @O2 your service is disgusting been on the phone on hold for 30 mins and you cut me off, refuse to speak to people unless they say they’re leaving you. I have to work in covid so should you! I’m paying over the odds for crap service. Sort it out!

  • rhiannonbate_ rhiannon (@rhiannonbate_) reported

    @O2 dishing out some of the worst customer service I've ever experienced 🥴

  • Richard97324518 Richard Hardy (@Richard97324518) reported

    @O2 Hello, signed up for a new contract which was miss sold to me as there is no phone!!! Get me out of this contract! Been on the phone for 2 hours to be hung up on twice!!! Not impressed!!! Customer service absolutely non existent!. So disappointed, was excited started out new!

  • dig_magee Anthony Magee (@dig_magee) reported

    Don't bother recycling your phone in an upgrade as a valued customer. My device 12mth old - reduced from £331 to £62. I challenged it no response after being promised. @O2 evidently making its money now from scamming honest customers. Order num 3106810 if you want to sort it @O2

  • helenkerr23 Helen (@helenkerr23) reported

    After over 20 years of loyalty I am officially saying goodbye to @VodafoneUK! New phone order direct from @Apple and new SIM card from @O2. Saving over £20 a month & maybe I will get to deal with a real person if I have an issue rather than the worlds most annoying bot TOBI!!

  • peterthepig Lord, such screaming! (@peterthepig) reported

    @O2 Hi I have an O2 MIFI dongle that gets an automatic 1Gb update applied each month... how can I stop that as I am paying for it but I can't use it in lock-down?

  • Jadeeeyy09 jade (@Jadeeeyy09) reported

    @O2 can’t get a hold of anyone to speak about my bill? Clicking on support just takes me in a loop, ridiculous.

  • Jordyy013 j (@Jordyy013) reported

    @O2 So i would be able to cancel without any extra costs after the 26th of this month? And would my data still work in europe or do i need to pay for roaming?
