Business taking advantage of hurricane victims?

My daughter, on the Tx coast, was without power for 19 days, from Sept. 11 through Sept 30. Now Centerpoint sends her an electric bill for $215.00, claiming she used only 100 kilowatt hours of power LESS in those 19 days without power than she used in all of August.(anyone know what August in Tx is like?). This on top of over $700 she spent in gasoline to keep a generator going for those 19 days. She contacted Centerpoint and they essentially blew her off saying "Well, that's what your meter read".

I think Centerpoint is trying to recoup their losses in extra men and man hours to restore all this power, and I seriously doubt my daughter is the only one getting bills like this. People who are struggling to rebuild and continue on after Ike do not need this added (and I think fabricated) expense. To whom or to what regulatory agency can we complain? .What can we do?
