    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 hi there, is it true you are currently able to buy people out of existing phone contracts if they switch to you? If so, any link with info about this or a name for this service? Thanks...
