I don't understand!

On friday the heat wasn't working so we called the home warranty company and the guy came out and supposedly fixed it. So yesterday when our heat came on the whole house filled with the smell of gas really fast! So we turned off the heat and opened the windows. After about 1/2 hour the smell was gone. We couldn't find the source of the problem so we left the heat off and went to church. Dan and my dad came back to try to figure it out. The thought it might just be some oil that the home warranty Friday. Later last night the smell was starting to get strong again. Dan called the home warranty company again and they said that heater guys probably wouldn't call us back until morning. Ok this is an emergency! Still they said they wouldn't call back until the morning. So for a company that claims to have 24 hour emergency service....they lied! We called our normal heater people and they came out with in 1 hour. We had a bad gas leak and our heater was not properly put back together. We had this ( much better repair guy ) document what happened and we'll see what we can do. I will never use the home warranty again! Thank goodness we don't think we were breathing in the gas too much since it was only coming out when the heat was on and it was warmer this weekend and we weren't home a lot!
