It is IGS Energy trying to sign up for their gas supplier company.

I don't know who this is

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.

Answered phone and no one on other end?!
