They sell windows etc. and even when you tell them to stop calling, they continue to call.  From what I've heard they're not a company I would care to do business with.  I don't answer anymore.

They keep calling.  I told them I'll never do business with anyone who STEALS from me by using MY PHONE that I PAY FOR in order to try and SELL me something (which, by the way, I don't need).

Complaint filed with FTC.
