    @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.

    @O2 Data is unusable where I am (Milan). As stated, I get 3G but can’t use it, all apps say phone is not connected to network. Irony is my wife is with @tescomobile and is getting 5G. Crossed into Switzerland today and got 5G halfway up a mountain but can’t use phone in Milan. 🤷

    The @O2 network has to be the worst ever. Even with a strong 4G signal, you still can’t get any data use!!! Certainly over subscribed. #notfitforpurpose #OFCOM

    @O2 2/2 from the o2 shop in Durham, he couldn't have been more helpful and did go over and above to help me this morning!

  • michelle_moomin Michelle Annie (@michelle_moomin) reported

    @O2 Absolutely shocking service at your Cribbs Causeway branch. So much so, a lady followed me from the store to say she had the same issues with them.

    @O2 Apologies. With the fold you don’t offer loss or theft. Only accidental damage

  • JamRuler89 James (@JamRuler89) reported

    @O2 Barely getting 3G while my wife is getting 5G on another network. Why can’t O2 improve in Lanarkshire?

  • tony_sutton Tony Sutton (@tony_sutton) reported

    Paid for 24 hours of Data SIM with @O2 which was activated straight away and clock counting down. Never worked, even after many device reboots and trying various O2 profiles. Tweeted & DM'ed @O2 - no reply. 24 hours is expiring soon. Waste of money. :/

  • Itslaurajane89 Laura Jane Minto (@Itslaurajane89) reported

    @O2 It's OK, I've been into my local o2 store this morning. Turns out @SamsungUK just lies to their customers and you don't take a contract out with o2 tiu just their network, turns out samsung use a third party network provider! However do want to give a shout out to Jack from the

    @kellyja90235455 @O2 Me too! Two contracts taken out fraudulently and can’t speak to customer services unless I pay the fraudulent account! Seems to have happened to lots. I’ve never been an o2 customer! So stressful

    @O2 my voucher for a sausage roll said it had been used but I never used it yet
