  • doncmccall Don McCall (@doncmccall) reported

    @O2 super disappointed in you. Ordered my Apple Watch upgrade from store. Only to be told because they have one, and I ordered online, I can’t have it. I’ve just ordered an Oppo find pro x5. Watch and this phone will be going back. Dreadful customer service.

  • clf7ey Clare Forrester-Shufflebottom 👩‍❤️‍👩 (@clf7ey) reported

    @O2 still having problems with my mobile data. I’m getting seriously fed up of not being able to do the simplest of things like accessing my gym log in.
