Unsolicited Calls

Have not done business with this company, but have received several calls.  Caller ID comes up as "New York Call".  I googled the number, it comes up as a vintage children's clothing store.  I think this is an overseas boiler room routing through a U.S. phone number.  Have emailed the clothing store with this information.  I've asked them to stop calling, some of the solicitors are verbally abusive and use obscenities.
