    @O2 when I upgraded my tariff last year I should have had a 25% emergency service discount added but I have just checked my bill and it doesn’t appear to ever have been added. How do I go about doing this?

    @O2 This is what I’m saying, I did this but it has never been included in my bill. So are you saying that now it’s been nearly a year it cannot be re-added?

    And there I was feeling good about moving to @O2! Trying to order additional SIM cards for my family members in my account and due to your credit check process it’s locked me for 30 days due to my SIMs order! Argh. Then, you drop my customer support call and don’t ring back!

    @O2 hi there. My husband has had no signal for the entire day, not even to text. Are there known issues?
