  • 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!

  • 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

  • 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

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

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

  • 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

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • 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

  • 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!

  • 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

  • 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

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

  • Swell09 Swell ✌🏻 (Pronoun: She/Her) (@Swell09) reported from Birkenhead, England

    @O2 hey folks are there any issues with the network today? My partner has no signal and can’t receive calls.

  • rbarkley82 Robert Barkley (@rbarkley82) reported

    extremely disappointed in @O2 yet again... I upgraded online and paid for delivery before 12noon today... Phoned DPD who said they dont do a pre-12 delivery service... so what did I pay £5.99 for? and to top it all off, its not getting delivered until Monday!

  • harrisonmallor_ Mallory Harrison (@harrisonmallor_) reported

    @O2 your customer service is appalling. you’ve activated the wrong number and a customer service rep is nowhere in sight (yet no problem charging me). Have called and sat on hold for 32 minutes and counting, have tried online chat but it’s “unavailable” the app also unavailable

  • mckennajames227 James McKenna (@mckennajames227) reported

    @O2 TS25 5TG and TS27 3LB. Still no phone signal.

  • Meta4ltd Clare Whalley (@Meta4ltd) reported

    @O2 please help - I want to recycle an old phone (no battery) so how do I find an IMEI or model number to start the process? #makerecyclingeasy

  • AnjaHenschel Anja Henschel-Idriss (@AnjaHenschel) reported

    @O2 this must be one of the worst customer services I have experienced. For a week I have been trying to speak to someone. Chat is rubbish as automated & won't connect to a person. Shop refers to 202. 202 can't get 2 anyone, got hung up on & then ended in a loop to choose an opt.

  • el_lad67 BriBhoy (@el_lad67) reported

    @NameOfTheMaster @O2 …..but they can’t cancel the order until they get the phone back from the warehouse and that could apparently take 5 days. Absolute shambles of a company with absolutely no one taking responsibility and dealing with matters when things go wrong.

  • rbarkley82 Robert Barkley (@rbarkley82) reported

    @viennacup1 @O2 It was DPD in Mallusk that stated no pre12 delivery service from DPD NI

  • AndiLyth 🌻Andi Lyth🌻🇹🇷 (@AndiLyth) reported

    @O2 what’s going on with your service?

  • Elestial10 Erminia A. Yardley (@Elestial10) reported

    @O2 I know this is fraudulent as i never sent an mms and yes... I know fully well NOT to click on link. The header of the txt message I received is slightly different from the ones u send...
