Our bill for November 179.00 our bill December 464.00 there is no way thisis accurate! And no way to prove other wise. We have a detached garage same thing there. November bill 70.00 December bill 320.00 how is Ameren electric company allowed to rip customers off. If CuiverRiver was a choice it would be mine.
