I have been over charged by amerigas too. I just moved into town, when I did, i called and talk to Tabitha to Cancel my old service, she said that i wasn't going to owe much b/c I had paid a deposit of $170, last night, we get a call from amerigas claiming we owe them over $600! How does that happen in a matter of 3 buisness days? there is absolutly no way possible we could have used $400 worth of propane in a home we were no longer even staying in!
