They sent me an email to say they were reducing my DD; so I rang to ask them to put it back up.
I explained that in Aug 09 I owed no money, during the next year they put my DD down 3 times & in Aug 10 I owed over £300. Which is wrong because generally people use more elec in the winter.
& apparently because I joined at the wrong time of the year this will always happen, unless I ring twice a year
that is odd isn't it?
