I don't know about anyone else, but my energy company are rubbish at setting out a bill.
Take this October £66.00 energy grant. I received an email last week saying that the £66.00 had been credited to my account and will be used in my October bill.
Got my bill in today, £42.00 give or take a few pence. Which if I can do my sums correctly I am still £24.00 in energy credit. But nowhere on my account does it say this £24.00 will be rolled over the November, giving my £91.00 energy credit because it rises to £67.00.
Hopeless. Or is it me who's hopeless?
