    @Aerial_Direct @O2 I’ve spoken to Naomi on your team already. That’s was a useless ten minutes. Refused to tell me details of how to cancel - just threatened temrination fees. Offered renewal. Honestly she would have had to have offered a unicorn in a colour of my choice to get a renewal.

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport Just checked and its now saying the same for me! Apparently it takes a full 26 hours to get from Birmingham to Down 🙄

    Is @O2 poor for network coverage in the Greater Belfast area?

    @virginmedia since my virgin mobile UK signal has been shifted from piggyback Vodafone to @O2 it has been a complete disaster, constant signal dropping, constant WiFi calling cutting. This is before my account has been transferred to O2. Complete and utter rubbish

    Kudos to @O2 for customer service today. Recommend going via app ‘Start a Conversation’ section.

    @Aerial_Direct @O2 I’ve been onto your customer services. They refused to tell me how much it would cost to buy out this awful contract. Threatened termination fees from @o2. A retentions team will be in contact. 🙄 My family member *thought* she was with @o2 - misdirection from you of course. 🤮

    @kokeshimum @O2 It's terrible all over the North, O2 have got gradually worse now all the help moved abroad. After 25 yrs I'm leaving going to Movistar in Canaries.

  • Watch_n_Wait
    Martin Lee (@Watch_n_Wait) reported

    @kokeshimum @O2 Listen to any talk radio show and the regularity with which they "lose" guests and callers is embarrassing, and nearly all down to dodgy mobile connections. Sadly Brits gave up a really decent landline system for the "convenience" of mobile without thinking about quality.

  • StuartBain1986

    @o2 you’re 5g and general signal quality is god awful 👍 can’t wait to move network

  • simonbrown001
    SB (@simonbrown001) reported

    @kokeshimum @O2 Networks share infrastructure the networks are under invested. Buy a new phone from the network pay 70-80 a month even after phones paid off. They were minted not anymore. Most people I know including me buy a phone & pay 10-15-20 quid a month no contract

    @TeamAriana @O2 Team Ariana, please help me. I didn't get a ticket for the London concerts, and resale tickets are very expensive. I am a huge fan from France and my heart is broken.

    @Savplast60 @O2 How ******** do you make a **** mobile phone service about immigrants ffs. O2 are a private company you clown.

  • Me10Andy
    ME10Andy (@Me10Andy) reported

    @kokeshimum @O2 I think a lot of the issue is contention ratios in the UK. O2 has the coverage, but far too many people on it....not because O2 is particularly cheap, but the other main networks are now incredibly expensive.

    @jibbajabbba @kokeshimum @O2 EE sponsor or did sponsor Wembley Stadium, I’ve been with EE for years and every time I went to Wembley I could never get a signal, pretty poor showing if your name is all over the gaff
