Just got the same call with the "hi". Something tells me this is some sort of automated call. On a hunch, I called the number back and got a recording that said I had reached some sort of customer service line and if I wanted to be removed from their calling list to press 1, or to talk to an operator to press 2. Since i wanted to actually talk to someone and let them know exactly how annoyed I was, I pressed 2. I got a busy signal, then was hung up on.
