How can I get or buy this Whatsapp Contacts Filter software? Please advise.
You can get the application through its official website. I've searched and found that it's hosted on Eportwhatsappcontact website which you can access using the link posted below.
Official website: http://www.exportwhatsappcontact.com/
Note: The application looks shady, therefore I recommend installing an antivirus before you use the WhatsApp Contacts Filter application.
