    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

    @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

  • Kev73Watkins Kevin Watkins (@Kev73Watkins) reported

    @O2 any reason why the internet is soooo slow on my phone in Winchester? Has been for a while now, I can get a better signal in the middle of the Solent

  • LeftWingBill LeftWingBill #GTTO (@LeftWingBill) reported

    @O2 Hi I can't access help on th website. I'm trying to bring my number over from EE.

  • MDNAistheQueen Christine (@MDNAistheQueen) reported

    @WidowWanda @O2 Having the same issue here!

  • Loran_Dunn Loran Dunn (@Loran_Dunn) reported

    @O2 When is the service issue in Manchester (M19) going to be fixed? Phone has literally been unusable for calls for months! Seriously irritating.

  • whosaidwhat0 who said what (@whosaidwhat0) reported

    @o2 is by far the worst network in Cornwall. Awful coverage. Internet is so slow it doesn't work. Vodafone and EE are fine though. Starting to regret changing networks

  • fun2learn2be Matt Bruton (@fun2learn2be) reported

    @O2 you’ve cut me off for not paying my bill, yet it was paid. Your customer services phone number terminated the call no matter what option is selected and your web chat doesn’t work. Is Twitter really the place to do this?

  • Simon_Doddy Simon Dodd (@Simon_Doddy) reported

    @O2 Trying to change my billing date but your website keeps changing to a blank white page. Tried in Chrome and Firefox. Previously when trying this I ended up in an endless loop with no resolution so can't seem to change it.

  • HerveyBrookes Paul Hervey-Brookes (@HerveyBrookes) reported

    Why is the 4G signal so slow and bad - I’ve really noticed in the UK is really works quickly and every image remains pixelated. And thoughts @O2 I mean I know you like charging £60+ a month but could I have a service at least
