    @O2 Poor customer experience in-store today. Disappointed to say the least.

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    Anyone know a good Internet provider @virginmedia are toss also what a good phone provider an all cause @O2 are just as bad

  • dsparks83 Dave Sparks (@dsparks83) reported

    Don’t think I’ve ever used #O2Priority for tickets before but it’s clearly not fit for purpose. A publically accessible link from @O2 to @gigsandtours with no check on status as an O2 customer? A pretty lazy implementation and once on social media real customers had no chance

  • wardinouk1 ᴍᴀʀᴛɪɴ ᴡᴀʀᴅ (@wardinouk1) reported

    @O2 You cant sell out when ya website is a pile of ****....how difficult was it to set up a queue system like three mobile/ticketmaster had going on? Fairly simple process in the grand scheme of things

  • oxander92 Xander (@oxander92) reported

    @O2 Absolutely disgraceful service today. Anyone with two brain cells could have told you how "unprecedented" the numbers would be buying tickets for Peter Kay and yet you were still woefully underprepared. I (like most people) have been trying since 9:30am only to be let down.

  • Paula_H25 paula hudson (@Paula_H25) reported

    @O2 Not working very hard eh? I still can’t get on my app!

  • pageynails amie (@pageynails) reported

    @O2 tried for 8 hours never even got to log in #joke

  • BenjaminWebb4 Ben Webb (@BenjaminWebb4) reported

    @O2 You absolute *****. No one has been able to get on the app all day. Your service is horrendous, it’s laughable!

  • SamLndn L0ND0N89 (@SamLndn) reported

    @O2 Bit of a c*nt move not freezing the sale until you sorted your issues out to allow a fair attempt for everyone. Been on my phone since 10am trying to get them.

    @O2 What a load of horse ****.
