I think they must be, just checked my electricity bills from last year and there is a three month period (August - November 2013) that appears on two bills.
Bill 1 - Dated 23 August 2013 - 20 November 2013
Bill 2 - Dated 2 July 2013 - 7 February 2014.
Not happy at all, already got one problem escalated with them after a 90min phone call last week, looks like I`m on for another tonight.
