    @O2 why is it so hard to get in contact with a human? I'm trying to see if I can get Volt as an O2 and Virgin customer but can't get through to anyone and the website keeps going round in circles so I can't apply! Please help!

    @O2 Morning O2. I seem to have an issue with my mobile account with you. I have sent you a DM. Grateful if you could revert asap since I am concerned my account may be being closed incorrectly. Thanks!

    @O2 Hi I upgraded my phone yesterday, I'm using the same sim, but I can only make emergency calls. Do I need to use a new SIM or can you activate my current one, please?

    @O2 how do I cancel my Disney+ that I added free for 6mths when I received an offer from you. Disney+ states I have to do this via you but I cannot see it on my account. Thanks in advance for your help.

    @O2 The international calls are still not activated in the current plan. This situation has been going on for months. I cannot dial out internationally, the question is why. Last week you addressed this and the problem persists. Pls escalate this.

    @O2 are really annoying me. My phone won't charge I need to speak to someone and the phone keeps saying go online (which I have already done.) And putting the phone down on me.
