Calls multiple times. I usually don't answer, but this time decided to answer for the purpose of telling them to take me off their calling list. The man I spoke with was very pushy about selling me new insulation for my attic. As I was telling him for the third time that I wasn't interested and not to call me again, he hung up on me. I would never do business with a company who was as unprofessional as they are with such poor phone skills!
