Dominion East Ohio Gas trying to steal money from me and ruin my credit Richmond Virginia

Dominion had shut my gas service off 2 years ago because of a leak in the main line from the main shut off to the house. It has since been off yet they still send me bills estimated. I have called and told them they no longer supply gas to my house because of the leak and since then used electric heat. they said they would send someone out to check that it was off and asked if someone would be home that day. I took the day off work to be there an no one came i called them back they told me that it was on i told them no one came. I then called P.U.C.O. and they told me that was between the gas company and me.some help they were? since then my latest bill is $1,284.52 for something i never got. someone tell me what to do?
