    @O2 Cannot connect to network- was told to use only specific roaming partners. They don’t work. Impossible to get through to o2 from abroad- the number I have found does not work. What is the number to call for pay monthly customers to call from abroad that works???

  • kristof_vaughan Chris (@kristof_vaughan) reported

    @GarethTurpin @O2 We can decide what phone to use, when we want, but you still can't provide data connection at Bournemouth beach during the summer. Any more than about 100 people and it seems to fail to provide any internet service

  • GhadeerAhmed96 Ghadeer Ahmed (@GhadeerAhmed96) reported from Ash, England

    Will never get a contract via @O2 . The worst customer service I have ever received . Shocking!

  • davecoupland Coups (@davecoupland) reported

    @O2 having a terrible experience with services. My wife’s phone hasn’t been getting a signal for 2 months. She is being passed from pillar to post by store staff and customer services. Please help.

    @O2 Please see my tweet below. My problem can only be resolved by a human on the end of a phone with empathy for age related issues.

    @O2 OK, but that is unhelpful. I need it for this weekend, hence buying from you, because your website promised a particular service level. You'd appreciate it is a failure to match what was promised.

  • MrAndyWatson A n d y (@MrAndyWatson) reported

    Paying near £200 a month with @O2 to have zero signal and 3G in Northern Ireland and Birmingham. Imagine having to buy a Vodafone pay and go SIM card. Not just my line friends/family also. A customer over 18 years on contract. Can other networks buy you out of contract?

  • PS_ACE Parit Shah (@PS_ACE) reported

    @O2 @O2 kinda pointless asking me to DM you so can help further and then not actually helping. I've sent all the security details you've asked for over a day ago and had literally nothing back from you.

  • DamzelinEssex Dami (@DamzelinEssex) reported

    I need @O2 to resolve this issue ASAP

  • DavidMorgan_CM David Morgan (@DavidMorgan_CM) reported

    @O2 what poor customer service at your #manchester #marketstreet store. I think you need to get a manager in the store and train staff in #CustomerService
