    @O2 terrible service guys!! My wife has returned a broken phone via o2 Insure and after 3 weeks still no phone. If she’s lucky they might send the broken one back, if they find it so she can try again. #terribleservice

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • SuarezFusters Jose Suarez (@SuarezFusters) reported from Ealing, England

    @O2 what happens with the network? In W139df #I don’t have 3g from yesterday and that is a nightmare.

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

    @O2 your customer service is an absolute joke.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • Borehamwoodbine Woody (@Borehamwoodbine) reported from Borehamwood, England

    In over 9 years with @O2 I’ve hardly ever needed customer services help and now after 3 attempts this year with little or no help I would just like to say thanks for nothing!

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • richardmorrisuk Richard Morris (@richardmorrisuk) reported from Richmond, England

    Hi @O2. So having cut me off twice on Sunday, told me to book a call, called but couldn’t deal with my issue , promised to call back within 48 hours (didn’t) - now I’ve had a call from a third party? Have you given them my data or have you been hacked?

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • ladidalimey david bryant (@ladidalimey) reported from Richmond, England

    @O2 my wife’s new phone has been waiting 4 days for her old number to port across. 202 have been no use. She is looking after her elderly parents and you have shut down BOTH her old phone and the new one. What are you going to do about it?

  • SuarezFusters Jose Suarez (@SuarezFusters) reported from Ealing, England

    @O2 anyone can please tell me what’s going on with the network in W13 9 I can’t receive message and call from last Saturday, I guess I need to change my provider.

  • _BethanB Bethan Bonsall (@_BethanB) reported

    Hi @O2 I’ve been struggling to get any signal in Cardiff recently and friends and family have been the same. It’s to the point where I have 0 bars and people can’t ring me at all. I know others are reporting the same so would be grateful to know what’s being done to resolve it?

  • JamesLark2 Cllr James Lark (@JamesLark2) reported

    @Elksy91 @O2 There all terrible. Spent hours dealing with Virgin . Finally won though and down to sheer persistence

  • HJDMISTASSAMIB Emz_1703 (@HJDMISTASSAMIB) reported

    @O2 why are you using DPD for your deliveries? Absolutely useless. I've just emailed a complaint to you guys after years as a customer, any idea how long it usually takes them to respond?

  • Baronvondoobie BARONVONDOOBIE (@Baronvondoobie) reported

    @O2 my phone all of a sudden won't allow me to use call waiting? Also when placing a call it will cut out when person answers and if they try and call

  • LauraRob95 La Robinson (@LauraRob95) reported

    So it has been THIRTY NINE (39 WHOLE DAYS and @O2 has yet to resolve or offer sufficient support for my complaint! 🙈 Disgrace!

  • georgeickeradio George Icke (@georgeickeradio) reported

    @O2 everytime I send a text from my new iPhone with you it marks as being not sent. I can't iMessage any of my contacts who have an iPhone despite imessage being on and my pre-porting number still shows as a way to contact me in iMessage! PLS help as I can't use my phone 😭😭😭

  • dingle1965 David Ingle (@dingle1965) reported

    @O2 How do I contact someone at your support team to discuss a bill query, I can't get through via the app?

  • cat_tequila tequila cat (@cat_tequila) reported

    @O2 I have been trying to rectify my issue below since 8.30 this morning via your messaging 'help' section as well as by phone, it is now 4.15pm and I am no closer to getting a second family SIM for my child.

  • cat_tequila tequila cat (@cat_tequila) reported

    @leemcbr37826036 @O2 This sounds familiar. I am now passed over to a third person, on hold again. The company is hopelessly under-resourced. I was pointed back towards the website which as I already know cannot provide a family SIM, poor info.

  • beth_hacking Betty (@beth_hacking) reported

    sick to death of @o2 connection. Paying nearly £80 a month for a phone that hardly ever has connection. Seems like a lot of people are getting rinsed here and with the money they’re making you’d think they’d be able to fix the phone mast which has ‘been down’ for months.
