JetBlue Airways does not have a dedicated physical office in Zagreb, Croatia, as they primarily operate out of U.S. hubs; for support, you should use their online resources (jetblue.com) or call their 24/7 customer service at 1-866-829-1086 for booking or managing flights, especially for tickets purchased via third parties like Expedia or Priceline, though expect a service fee for those.
