    @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.

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

    @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

  • PlexiThor Cryptop (@PlexiThor) reported

    @O2 @virginmedia Please just allow your customers to modify/suspend and cancel unwanted services and contracts online. I shouldn't have to haggle with customer services. A lot of customers will switch to other providers who offer the simplicity to make choices. @Tesla mobile

  • MaxKelsey23 Max Kelsey (@MaxKelsey23) reported

    @theswirly @O2 Prices are a joke. Problem is there's plenty of affluent rugby fans who will pay them, so the RFU never see the issue.

  • tudorgurl MJB 🤍 (@tudorgurl) reported

    @ShaziaSaleemLDN @O2 Crashing, error messages, ticketmaster packages not even available. **** Show

  • TomParry93 Tom Parry (@TomParry93) reported

    Good morning @virginmedia Sadly I’m forced to make my complaint about your appalling service public. As explained multiple times, I’ve received a ludicrous bill of £298.59 for a broadband/SIM package which I cancelled when yourselves and @O2 failed to deliver either service. 1/3
