I was wondering if anyone was aware of this. Last month I queried my bill increase and too my shock my gas bill had increased by 24%. I queried this with the cust services rep and she told me its because other parts of the country have different rates.
When I said I demand to be on the same rate as everybody else for the same gas, service etc. I raised a complaint and still not heard anything. So it looks like my increase is subsidising someone else in another part of the country.
