Appstar Financial Company bought our business info from 3rd party and no calls everyday and is extremely rude , Internet

This company bought our business' information from a 3rd party and has been calling our office everyday for the last year or so not asking to speak with anyone but just blurting out a name and when we tell them that the person is not available to please leave a message they either hang up on us or they are very rude like today's experience..  the woman just said (Owner's Name) I proceeded to tell her that he is not available but she then cut me off and asked very rude like "if there is another owner" I told her no but if she would let me speak i can take a message and get it to him but she did not hear any of that because she had hung up when I said no there is only one owner.  I find these calls to be very rude and bothersome.  We run a very busy office here and to be bothered by a telemarketer that wont let you even talk or better yet have the common sense to call a business and be professional about your call is an extreme waste of our time.  Some one needs to put companies like this in check and let them know that if you are cold calling to get someone's business you should be courteous and respectful of the person you are calling or you end up not only not getting their business but bad referral and reviews from those businesses you have bothered.
