It is great you got your credit, but as a general statement the electricity retailers have all sorts of hidden gems to get a dollar. Some of them include discounts on use but not on service, and some do not give any credit for the final bill.

It is all in the T&C and knowing them is the secret to getting what one is entitled to, or giving them a bye, and finding out one has not read as diligently as they should have.
