Sick of these calls. I tell them I don't have natural gas (although my husband has plenty at times) and that we use propane, but the jerks still call. Because of this, I would not recommend this company to do business with, they are obviously boneheads, stupidly persistent while in error, and wasting everyone's time. It would be a bad scene to be billed from them based on their errors telephoning people that could never be customers anyway.
