    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • anthonyseddon Anthony Seddon (@anthonyseddon) reported

    @O2 Load of absolute shite that I was on the app for a good 8 hours never got on once load of lies that

  • AndrewP52229669 Pez Beer (@AndrewP52229669) reported

    @O2 Absolutely shameful O2 !!! For a site down all day to say all tickets are now sold is unbelievable. If these tickets end up on resale sites at inflated prices you deserve to have your license stripped !!!

  • Paul_PBK Paul B (@Paul_PBK) reported

    @O2 Absolutely a case of false advertising, leading customers to think they are getting an advertised service with their contracts and then not fulfilling it. I hope @NTSscamsteam or someone similar picks up on it. Your priority app and website were down all day for a lot of people.

  • stac_blundell stacey blundell (@stac_blundell) reported

    @O2 Tickets aren't being sold as your app is down for everyone not just the odd person! Those aren't actual O2 or virgin customers buying tickets there bots and people passing the system. You should cancel tickets unless they can instore with ID to prove there human or something

  • nickpebody Nick Pebody (@nickpebody) reported

    @O2 This is scandalous. I’m seriously considering leaving o2 and never coming back. How have you sold out all of your tickets when your website has been down all day? Who has bought them? I’ve seen them on resale sites. Something doesn’t sit right with me here @o2

  • georgia2311 Georgia 💙 (@georgia2311) reported

    @O2 Your app is still not working!

  • mh_07_jch Cher Hendley (@mh_07_jch) reported

    @O2 Really? And just how exactly has your allocation of tickets sold out when none of your genuine O2 priority customers could log into the app / website all day? This is an absolute joke @o2 @peterkay_co_uk Feels so great to be an O2 customer with priority access - NOT 🤬

  • GJS2010 G (@GJS2010) reported

    @O2 How can that happen when the site and app were down all day? I'm confused.

  • Richie0079 Richie (@Richie0079) reported

    @O2 A complete and utter shambles from you guys today. It's now 2am and the whole of Priority is still down. So people have been locked out of doing anything else as well. Your tickets sold out because bots bought them and they're now for sale elsewhere at inflated prices.

  • apmoore1976 Andrew Moore (@apmoore1976) reported

    @O2 How the bloody hell did they sell out. From 9am the website, app have been down. Hope your SRE engineering team have a word with themselves.
