irving Oil

I have been an Irving oil customer for over 20 years. I have leased my oil hot water tank for this amount of time paying 30$ a month. Thank to the government I qualified for a home heating grant which includes two heat pumps and an electric hot water heater. So I called Irving to have my hot water heater removed. They are charging me over 461$. Apparently because 3 years ago my water heater had to be replaced and it started a new contract which is totally not right. I still have my oil furnace which I still will need to by oil . This is despicable. Shame on you Irving oil.
